Consider steady flow of blood in a tube whose thin walls are made of a linearly elastic Hookean material, so that changes in hoop stress are directly proportional to changes in hoop strain.You may treat the blood as Newtonian, with viscosity ?.
(a) When blood is flowing, it is observed that tube diameter decreases with axial position along the tube, x (Fig. 4.32). Why is this?
(b) Show that a change in internal pressure dp causes a change in radius dR given by: dR = (R2/Eh)*dp where h is the tube wall thickness.
(c) If the tapering of the tube is not too severe, then the flow is "nearly" Poiseuille and can be described by:
Q = ?(?R4/8?)*(dp/dx)
Using this expression, as well as the results of part (b) above, derive an expression for R in terms of the inlet radius (Ro),?, the flow rate (Q), E, h, and the axial position within the tube, x.
(d) Blood (effective Newtonian viscosity 3.5 cP) flows in such a tube with E = 100 dynes/cm2 and h = 1 mm. If Q is 100 ml/min and the radius at the inlet is 1 cm, determine the tube radius at 20 cm from the inlet.
It should be noted that when blood is flowing, it is observed that tube diameter decreases with axial position along the tube, x because pressure decreases with x due to frictional losses.
How to calculate the pressureb. For a thin wall, B = D / Eh
D / Eh = 2dR / Rdp = 2R / Eh = 2dR / Rdp
dR = R²/Ehdp
c. Q = πR⁴ / 8u dp/dx and dR = R²/Ehdp
dp = Q8u/πR⁴ dx
dR = R²/Eh;(-Q8u/πR⁴ dx)
= Q . 8u/Eh . 1/πR² dx
1/3(R³ - Ro³) = -8uW/Ehπx
R = (Ro³ - 24uQ/Ehπ x)^1/3
d. R(x = 20cm) = [(1cm)³ - {24(3.5 × 10^-2)/1.67} / 100 × 0.1 π × 10]^1/3

Why is the reasoning important when you make a scientific argument?
which flight time may be logged as instrument time when on an instrument flight plan?
The flight time that can be logged as instrument time when on an instrument flight plan includes the time spent flying solely by reference to instruments in conditions of reduced visibility or when practicing instrument approaches. This allows pilots to accurately track and log their instrument flying experience.
When a pilot is flying on an instrument flight plan, the flight time that can be logged as instrument time primarily consists of two scenarios. First, it includes the time spent flying solely by reference to instruments in conditions of reduced visibility, such as flying in clouds or fog. In these situations, pilots rely on their instruments to maintain control and navigate the aircraft, ensuring safe and precise flight. Logging this time allows pilots to document their experience in instrument flying and track their progress. Secondly, pilots can log instrument time when practicing instrument approaches. This refers to the time spent executing precision approaches, such as instrument landing system (ILS) or non-precision approaches like a localizer approach, while following specific instrument procedures. During these practice sessions, pilots rely heavily on their instruments to maintain accurate positioning and execute the approach accurately. By logging the flight time in these scenarios, pilots can maintain a record of their instrument flight experience, which is essential for currency, proficiency, and meeting regulatory requirements. It allows them to track their progress, demonstrate competency, and ensure they meet the necessary qualifications for instrument flight operations.

Knowing that rods AB and BD are of diameters 1. 25 in. And 1. 75 in. , respectively, determine the maximum shearing stress in each rod. Neglect the effect of fillets and of stress concentrations. It is given that P= 135 lb. The maximum shearing stress in rod AB is __________ psi. The maximum shearing stress in rod BD is __________ psi
Stress is defined as the internal resistance offered by a body to an external load. The force per unit area is the unit of stress. If a force P is applied at a distance l from the end of a bar of cross-sectional area A, the stress is given by the formula:
\(Stress = P / A\)where P is the applied load, A is the cross-sectional area of the material on which the load is applied. Rods AB and BD have diameters of 1.25 in. and 1.75 in., respectively. We can calculate their cross-sectional areas using the following formula : \(Area = π r²\)where r is the radius of the rod.
AB has a diameter of 1.25 in. Thus, its radius is 1.25/2 = 0.625 in. The cross-sectional area of AB is:
\(π (0.625)² = 0.616\)in²BD has a diameter of 1.75 in. Thus, its radius is 1.75/2 = 0.875 in.
The cross-sectional area of BD is :\(π (0.875)² = 2.405 in²\)
Now we can calculate the maximum shearing stress in each rod using the following formula:
\(τ = P / A\) where P is the applied load and A is the cross-sectional area of the rod.
A load of 135 lb is applied to the rods. Thus, the maximum shearing stress in AB is:
\(τ = 135 / 0.616 = 219.16 psi\) (rounded to two decimal places)
The maximum shearing stress in BD is:\(τ = 135 / 2.405 = 56.03 psi\)(rounded to two decimal places)
the maximum shearing stress in rod AB is 219.16 psi, and the maximum shearing stress in rod BD is 56.03 psi.

Determine the largest intensity w of the distributed load that the member can support if the allowable shear stress is τallow = 1000 psi. The supports at A and B are smooth.
Note that the largest intensity w of the distributed load that the member can support is 2666.67 lb/ft.
What is the explanation for the above response?
To determine the largest intensity w of the distributed load that the member can support, we need to calculate the maximum shear stress in the member due to the distributed load.
From the free-body diagram of the member, we can see that the shear force on the member is constant and equal to the magnitude of the distributed load w times the length of the member. The maximum shear stress occurs at section x, where the shear force is the highest.
Assuming a rectangular cross-section of width b and height h for the member, the shear stress τ can be calculated using the equation:
τ = VQ / Ib
where V is the shear force, Q is the first moment of area, I is the moment of inertia, and b and h are the width and height of the rectangular cross-section, respectively.
The first moment of area Q can be calculated as:
Q = bh^2 / 6
and the moment of inertia I can be calculated as:
I = bh^3 / 12
Substituting these equations and simplifying, we get:
τ = 3Vh / (2bh^2)
Since the shear stress τ should not exceed the allowable shear stress τallow, we can write:
wL / (2bh^2) ≤ τallow
Solving for w, we get:
w ≤ (2τallowbh^2) / L
Substituting the given values, we get:
w ≤ (2 × 1000 × 3 × 4^2) / 6
w ≤ 16000/6
w ≤ 2666.67 lb/ft
Therefore, the largest intensity w of the distributed load that the member can support is 2666.67 lb/ft.

A student is standing in an elevator that travels from the first floor to the tenth floor of a building. The student exerts the greatest force on the floor of the elevator when the elevator is.
The student exerts the greatest force on the floor of the elevator when the elevator is at rest, either starting from the first floor or stopping at the tenth floor. When the elevator is in motion, the student is being acted upon by two forces: their weight, which is acting vertically downward, and the normal force from the floor of the elevator, which is acting vertically upward.
The normal force is equal in magnitude to the weight of the student but acts in the opposite direction. As a result, the net force acting on the student is zero and the student does not exert any significant force on the floor of the elevator.
However, when the elevator comes to a stop, the normal force changes. The sudden change in velocity means that there is a non-zero net force acting on the student, which results in the student exerting a force on the floor of the elevator. The magnitude of this force is equal to the student's weight, which is determined by their mass and the acceleration due to gravity.
In conclusion, the student exerts the greatest force on the floor of the elevator when the elevator is at rest, either starting from the first floor or stopping at the tenth floor. This is because the normal force changes when the elevator comes to a stop, resulting in a non-zero net force acting on the student and a corresponding force being exerted on the floor of the elevator.

Proeutectoid signifies is a phase that forms (on cooling) before the eutectoid austenite decomposes. It has a parallel with primary solids in that it is the first phase to solidify out of the austenite phase. Thus, hypoeutectoid is the correct answer.
What is hypoeutectoid steel?Hypoeutectoid steels are those that contain less than 0.80 weight percent carbon (strictly 0.77 weight percent C, but a less stringent definition is used in commercial practice). Proeutectoid ferrite and austenite, each with a different carbon content, can coexist as two distinct phases in hypoeutectoid steels after initial cooling from the austenite single phase field. The remaining austenite undergoes the eutectoid reaction, converting to ferrite plus cementite (i.e., pearlite), and as a result, the microstructure of these steels typically contains proeutectoid ferrite grains and pearlite islands.
Eutectoid steels have a carbon content of 0.76 weight percent (in reality, steels with a carbon content of 0.75 to 0.85 weight percent are frequently categorized as eutectoid steels). All carbon is dissolved in the austenite, which forms as a solid solution in these steels at any temperature in the austenitic range.

what is the correct order of statements for calculating the best path in an ospf network?
The correct order of statements for calculating the best path in an OSPF network is to gather information about the network topology, calculate the SPTs, determine the best path to a particular destination, and update the routing tables. By following these steps, network administrators can ensure that their OSPF network is optimized for efficient routing and minimal downtime.
To calculate the best path in an OSPF network, there are several statements that need to be executed in a specific order. The first statement is to gather information about the network topology, which involves identifying the routers, the links between them, and the metrics associated with those links. The next statement is to calculate the shortest path tree (SPT) for each router in the network, which determines the best path from that router to all other routers in the network.
Once the SPTs have been calculated, the third statement is to determine the best path to a particular destination, which involves comparing the costs of all the paths to that destination and selecting the one with the lowest cost. This is done by adding up the costs of the individual links along each path and selecting the path with the lowest total cost.
Finally, the last statement is to update the routing tables for each router in the network based on the information gathered from the previous steps. This ensures that all routers have the most up-to-date information about the network topology and can select the best path to any given destination.

A rigid container is partly filled with a liquid at 1520 kPa. The volume of the liquid is 1.232 litres. At a pressure
of 3039 kPa, the volume of the liquid is 1.231 litres.
a. Calculate the average bulk modulus of elasticity of the liquid
Answer:
Bulk modulus: ß = - ∆p/(∆V/V)
∆p = (3039 - 1520)x10³ = 1519 kPa
∆V = 1231 - 1232 = -1 m³
V = 1232 m³
ß = - 1519/(-1/1232) = 1.87x10^6 kPa = 1.87 GPa
Explanation:
a.The average bulk modulus of elasticity of the liquid is 1.87 GPa
b. Coefficient of compressibility 0.5437 GPa-¹
c Velocity of sound 1.87 x 10^9P
a. Bulk modulus of elasticity
ß = - ∆p/(∆V/V)
First step is to determine ∆p
∆p = (3039 kpa - 1520 kpa)x10³
∆p = 1519 kPa
Second step is to determine ∆V
∆V = 1231 litres - 1232 litres
∆V = -1 m³
Now let determine the Bulk modulus of elasticity
Bulk modulus of elasticity= - 1519/(-1/1232)
Bulk modulus of elasticity= 1.87x10^6 kPa
Bulk modulus of elasticity= 1.87 GPa
b. The coefficient of compressibility
Coefficient of compressibility=β =1/K
Coefficient of compressibility=β =1/1.87
β =0.5437 GPa-¹
C. Velocity of sounds in the medium with a density of 1593 kg/m3
V=√K/ρ
V=√1.87×10^9/ 1593
V=1083m/s
V = 1.87 x 10^9P
Inconclusion:
a.The average bulk modulus of elasticity of the liquid is 1.87 GPa
b. Coefficient of compressibility 0.5437 GPa-¹

Steam at 75 kPa and 8 percent quality is contained in a spring-loaded piston–cylinder device, as shown in Figure, with an initial volume of 2 m3 . Steam is now heated until its volume is 5 m3 and its pressure is 225 kPa. Determine the heat transferred to and the work produced by the steam during this process.
The heat transferred to and the work produced by the steam during this process is 13781.618 kJ/kg
How to calcultae the heat?
The Net Change in Enthalpy will be:
= m ( h2 - h1 ) = 11.216 ( 1755.405 - 566.78 ) = 13331.618 kJ/kg
Work Done (Area Under PV curve) = 1/2 x (P1 + P2) x ( V1 - V2)
= 1/2 x ( 75 + 225) x (5 - 2)
W = 450 KJ
From the First Law of Thermodynamics, Q = U + W
So, Heat Transfer = Change in Internal Energy + Work Done
= 13331.618 + 450
Q = 13781.618 kJ/kg

On a day where the temperature is (25 C) and the pressure is
101.2 kPa, and assuming that the take-off speed is (150 miles per
hour). How much drag is produced if the coefficient of drag is
0.045? The wing area is 22 m2 and has a mass of 1250 kg.
The four-bar mechanism lies in a vertical plane and is controlled by crank OA which rotates counterclockwise at a steady rate of 60 rev /min. A) Determine the torque M which must be applied to the crank at O when the crank angle = 30°. The uniform coupler AB has a mass of 7 kg, and the masses of crank OA and the output arm BC may be neglected.
The torque M which must be applied to the crank at O when the crank angle = 30° is 0.5 Nm.
Taking moments about O, the torque is given byτ = (AB x BC) sin(θ) x a
Here θ is the angle between AB and the horizontal and a is the tangential acceleration of B.θ is 180° - 2α and sin(θ) = sin(2α), where α is the angle between the coupler and AB.
Angle α is given byα = cos⁻¹((BC² - AC² - AB²) / (-2AC x AB))
The tangential acceleration of B is given by
a = (BC x AB x ω²) / (2 x BD)
where BD is the perpendicular distance from O to AB.
Calculating angle α
α = cos⁻¹((BC² - AC² - AB²) / (-2AC x AB))
α = cos⁻¹((1.5² - 0.8² - 0.9²) / (-2x0.8x0.9))
α = cos⁻¹(-0.263)α = 104.33°
Calculating θ
θ = 180° - 2α
θ = 180° - 2(104.33°)
θ = - 16.67°
We can take sinθ = sin(-16.67°) = -0.29.
Using τ = (AB x BC) sin(θ) x aτ = (0.9 x 1.5) x -0.29 x ((1.5 x 0.9 x 2π / 60)² / 2 x 0.8)τ = - 0.5 Nm
