A cylindrical tank is required to contain a gage pressure 560 kPa . The tank is to be made of A516 grade 60 steel with a maximum allowable normal stress of 150 MPa . If the inner diameter of the tank is 3 m , what is the minimum thickness, t, of the wall
Answers
Answer:
5.6 mm
Explanation:
Given that:
A cylindrical tank is required to contain a:
Gage Pressure P = 560 kPa
Allowable normal stress \(\sigma\) = 150 MPa = 150000 Kpa.
The inner diameter of the tank = 3 m
In a closed cylinder there exist both the circumferential stress and the longitudinal stress.
Circumferential stress \(\sigma = \dfrac{pd}{2t}\)
Making thickness t the subject; we have
\(t = \dfrac{pd}{2* \sigma}\)
\(t = \dfrac{560000*3}{2*150000000}\)
t = 0.0056 m
t = 5.6 mm
For longitudinal stress.
\(\sigma = \dfrac{pd}{4t}\)
\(t= \dfrac{pd}{4*\sigma }\)
\(t = \dfrac{560000*3}{4*150000000}\)
t = 0.0028 mm
t = 2.8 mm
From the above circumferential stress and longitudinal stress; the stress with the higher value will be considered ; which is circumferential stress and it's minimum value with the maximum thickness = 5.6 mm

Answers
Answer:
C. The Employer
Explanation:
Under OSHA's Confined Space Standard, it is the responsibility of the "employer" to identify or evaluate the spaces whether they are "permit spaces" or "confined spaces." These spaces have serious safety hazards or health hazards. Examples: tanks, vessels, pits, underground vaults, and the like.
The employers need to disclose the information of the permit spaces and their risks to the employees. Thus, he should have a written permit of the permit space if he will be allowing the employees to enter. It is also the employer's responsibility to reduce the hazards imposed to the employees such as verifying the entry conditions that are acceptable, making sure the permit space is isolated, providing barriers, etc.

D. a refrigerant leak.
Answers
An oily dust spot on a condenser or evaporator coil can be an indication of non-condensables in the system.
What takes place if non-Condensables are still present in the system?High head pressure and condensing temperature will arise from the system's non-condensables. High side pressure fluctuations may also be brought on by them. Higher compression ratios ultimately have a negative impact on cooling capacity and efficiency.
How do non-condensables in the system manifest themselves?It is challenging to pinpoint the source of this issue in a system with non-condensables since it will have poor cooling and excessive humidity levels while appearing to be in regular operation. Suspect the presence of non-condensables if a system exhibits subcooling, superheat, and system pressures/temperatures that simply don't make sense.

An engineer places a small sample of a material on a horizontal disk whose surface is made of another material and then rotates the disk from rest with a constant angular acceleration of 4 rad/s2. Assuming that the coefficient of static friction between the sample and disk is 0. 2, what is the angular velocity of the disk at the time instant when the sample starts slipping on the disk?.
Answers
The critical value of the angular velocity obtained just before the slipping starts is the answer to this question and it is \(\bold{\omega = \sqrt{\frac{\mu.g}{r}}}\).
Let's consider the sample to be a point object.There are 2 forces acting upon the sample when it is on the plane and rotating: the normal force from the plane and the friction force directed to the centre of the rotating axis.This friction force provides the centripetal force needed to continue the rotation on the disk keeping itself at rest on the disk relative to it.The reason for a slip is due to the lacking of this friction so that it is no longer capable of providing the required amount of centripetal force in the form of friction.The maximum friction is simply \(f_{max} = \mu_s.R\) where \(R\) is the normal force on the sample and \(\mu_s\) the coefficient of static friction. By the vertical equilibrium \(R = mg\) and that gives \(f_{max} = \mu_s. mg\)The proper condition to continue the rotation without slipping is as follows and the critical value of angular velocity can be found from it.
\(\begin{aligned}\\\\F &= ma\\\\f_{max} &\geq ma\\\\ \mu_s.mg &\geq m.r\omega^2\\\\\omega &\leq \sqrt{\frac{\mu_sg}{r}}\\\\\omega_{critical} &= \sqrt{\frac{\mu_sg}{r}}\end{aligned}\)
The critical angular velocity depends only on these parameters and for a given system it is dependent on where it is primarily placed from the centre of rotation (this question lacks this piece of data by the way).So this is the answer to this question and with the data for the constant angular acceleration, you can calculate how long it would take from the startup or how many rotations it would take until the point of slipping.For that, you can employ the formulae \(\omega = \omega_0+\alpha.\Delta t\) and \(\omega^2 = \omega^2_0+2\alpha .\Delta \theta\) respectively by putting \(\omega = \omega_{critical}\).#SPJ4
what are the reasons why fine grained of alkali igneous rocks can not be used in cement
Answers
Fine grained of alkali igneous rocks cannot be used in cement because of the volume expansion caused by the Alkali-silica reaction, fine-grained igneous rocks cannot be used as aggregates in cement.
What does fine grained mean in an igneous rock?Extrusive igneous rocks have a fine-grained or aphanitic texture, with grains that are too small to see without a magnifying glass. The fine-grained texture suggests that the rapidly cooling lava did not have enough time to form large crystals. A petrographic microscope can be used to examine these tiny crystals.
The texture of an igneous rock (fine-grained vs coarse-grained) is determined by the rate at which the melt cools: slow cooling produces large crystals, while fast cooling produces small crystals.
The chemical reaction that occurs in both alkali cations and hydroxyl ions in the pore solution of hydrated cement paste and certain reactive silica phases present in concrete aggregates is known as the alkali-silica reaction (ASR).

How many edges does a full binary tree with 1000 internal vertices have?
Answers
A full binary tree with 1000 internal vertices has 2(1000) = 2000 edges.
A full binary tree is a binary tree in which each internal vertex has exactly two children, and each leaf node has no children. In a full binary tree, the number of leaf nodes (L) is one more than the number of internal vertices (I). Therefore, we have:
L = I + 1
Given that there are 1000 internal vertices, we can calculate the number of leaf nodes:
L = 1000 + 1
L = 1001
Now, we can find the total number of vertices (V) in the tree by adding the number of internal vertices and leaf nodes:
V = I + L
V = 1000 + 1001
V = 2001
Since a tree has one less edge than the total number of vertices, the number of edges (E) in the tree is:
E = V - 1
E = 2001 - 1
E = 2000
So, a full binary tree with 1000 internal vertices has 2000 edges.

A bearing with an inside diameter of 1/14 inches is found to be 0. 008 inch oversize for the armature shaft. What should the diameter of the bearing be to fit the shaft? Allow 0. 002-inch clearance for lubrication. ________________
Answers
The required diameter of the bearing for fitting the shaft, considering oversize and lubrication clearance, is determined to be approximately 0.07742 inches based on the given specifications and calculations.
An inside diameter of bearing = 1/14 inches. Oversize for armature shaft = 0.008 inches. Clearance for lubrication = 0.002 inches. Let the required diameter of the bearing be d inches.
To fit the shaft, the diameter of the bearing should be d - 0.002 inches. (clearance for lubrication). The given oversize of the bearing for the armature shaft is 0.008 inches. So, we have:d - 0.008 = 1/14 - 0.002.
Multiplying throughout by 14, we get: 14d - 0.112 = 1 - 0.02814d = 1 - 0.028 + 0.112d = 1.084/14d = 0.07742 inches. Thus, the diameter of the bearing should be 0.07742 inches.

a highway produces SPL of 64 dB at a distance of 250 ft from the highway, determine the SPL at the following distances from the highway:
A) 150 ft under hard surface condition
B) 500 ft under soft surface condition
c) 1500 ft under soft surface condition
Answers
Using the Inverse Square Law, the SPL at 150 ft under hard surface condition is 58.57 dB, at 500 ft under soft surface condition is 61.98 dB, and at 1500 ft under soft surface condition is 51.02 dB.
Given:
Distance of the highway (r) = 250 ft
Sound Pressure Level (SPL) at distance r (L1) = 64 dB
Sound Pressure Level follows the Inverse Square Law. According to this law, the SPL decreases by 6 dB when the distance is doubled, and it increases by 6 dB when the distance is halved.
Mathematically, it can be written as,L1/L2 = (r2/r1)² Where,
L1 is the SPL at distance r1 and L2 is the SPL at distance r2.Substituting the given values and solving, we get the following:
For A) 150 ft under hard surface condition: L2 = L1 - 20 log(r2/r1) dB where
r1 = 250 ft, r2 = 150 ftL2 = 64 - 20 log(150/250) = 58.57 dBFor B) 500 ft under soft surface condition: L2 = L1 - 20 log(r2/r1) dB where
r1 = 250 ft, r2 = 500 ftL2 = 64 + 20 log(250/500) = 61.98 dBFor c) 1500 ft under soft surface condition: L2 = L1 - 20 log(r2/r1) dB where
r1 = 250 ft, r2 = 1500 ftL2 = 64 + 20 log(250/1500) = 51.02 dBHence, the SPL at distances 150 ft under hard surface condition, 500 ft under soft surface condition, and 1500 ft under soft surface condition are 58.57 dB, 61.98 dB, and 51.02 dB, respectively.
