A water turbine is to be designed to produce 27MW when running at 93.7 rev/min
under a head of 16.5m. A model turbine with an output of 37.5kW is tested under
dynamically similar conditions with a head of 4.9m . Calculate the:
a. model speed; b. scale ratio; c. assuming a model efficiency of 88%, estimate the volume
flow rate through the model; and d. if it is estimated that the force on the thrust bearing of
the full-size machine is 7.0GN , determine the bearing thrust of the model.
The Answers for the given question are as follow:
a. The model speed is approximately 31.62 rev/min.
b. The scale ratio is approximately 0.0417.
c. The estimated volume flow rate through the model is approximately 943.44 m^3/s.
d. The bearing thrust of the model is approximately 9.72 kN.
To calculate the required values for the water turbine model, we can utilize the concept of dynamic similarity.
a. To find the model speed, we can use the principle of geometric similarity, which states that the ratio of speeds is equal to the ratio of the square roots of the head. Thus:
Model speed = (√(Model head))/(√(Full-size head)) * Full-size speed
= (√4.9/√16.5) * 93.7 rev/min
= 31.62 rev/min
b. The scale ratio can be determined using the equation:
Scale ratio = (√(Model power))/(√(Full-size power))
= (√37.5kW)/(√27MW)
≈ 0.0417
c. To estimate the volume flow rate through the model, we can use the power equation:
Model power = (Model efficiency) * (Volume flow rate) * (Model head) * (Gravity)
37.5kW = 0.88 * (Volume flow rate) * 4.9m * (9.81m/s^2)
Solving for the volume flow rate:
Volume flow rate = 37.5kW / (0.88 * 4.9m * 9.81m/s^2)
≈ 943.44 m^3/s
d. To calculate the bearing thrust of the model, we can use the principle of force similarity:
Bearing thrust model = (Model power / Full-size power) * Full-size bearing thrust
= (37.5kW / 27MW) * 7.0GN
≈ 9.72kN

A 1-mm-thick sheet of FCC iron is used to contain nitrogen in a heat exchanger at 1200 °C. The concentration of N at one surface is 0.04 atomic percent and the concentration at the second surface is 0.005 atomic percent. Determine the flux of nitrogen through the foil in N atoms/(cm2 · s)?
The flux of nitrogen through the foil is 1.225 x \(10^{-7\) atomic/(\(cm^2\)*s).
What is electric flux?The electric flux is defined as the total number of electric field lines passing through a given area in a given unit of time.
To solve this problem, we can use Fick's first law of diffusion, which relates the flux of atoms to the concentration gradient:
J = -D x (dC/dx)
Where J is the flux of atoms (in atoms/(cm^2*s)), D is the diffusion coefficient, C is the concentration of nitrogen (in atomic percent), and x is the distance across the foil.
We can assume that the diffusion coefficient for nitrogen in FCC iron at 1200 °C is approximately 3.5 x \(10^{-7\) \(cm^2\)/s. We can also assume that the foil is flat and that the concentration gradient is uniform across its thickness.
Using these assumptions and the given concentrations, we can calculate the concentration gradient:
dC/dx = (0.04 - 0.005) / (1 mm) = 0.035 / 0.1 cm = 0.35 atomic percent/cm
Now we can plug in the values into Fick's first law of diffusion:
J = - (3.5 x 10^-7 cm^2/s) * (0.35 atomic percent/cm)
J = - 1.225 x \(10^{-7\) atomic/(\(cm^2\)*s).
Since the flux is negative, we can interpret this as meaning that nitrogen is diffusing from the surface with the higher concentration (0.04 atomic percent) to the surface with the lower concentration (0.005 atomic percent), as we would expect.
Therefore, the flux of nitrogen through the foil is 1.225 x \(10^{-7\) atomic/(\(cm^2\)*s).

What will be the volume of 1 L of liquid water at a pressure of 14.7 PSI if the pressure doubles and the temperature remains the same?
The volume of 1 liter of liquid water will remain unchanged when the pressure doubles and the temperature remains constant at 14.7 PSI.
The volume of a liquid, such as water, is generally considered to be almost incompressible. Therefore, when the pressure applied to a liquid increases while the temperature remains constant, the volume does not change significantly. This is known as the isochoric or constant volume condition.
In the given scenario, the pressure doubles from 14.7 PSI to 2 * 14.7 PSI = 29.4 PSI. However, since the temperature remains the same, the volume of the liquid water will not be affected. It will still be approximately 1 liter.
This conclusion is based on the fact that water is considered to be incompressible under ordinary conditions. In reality, there may be very small changes in volume due to the compressibility of water, but these changes are typically negligible and can be disregarded for most practical purposes.

Explain.?Martin wants to compare the weather in Oregon with the weather in Virginia. He looks at a weather chart showing the weather in Oregon during November and a weather chart showing the weather in Virginia during April. He also finds a precipitation map for Oregon for July and a temperature map for Virginia for July. Will Martin be able to make a good comparison of the weather in the two states? Explain?
Martin's ability to make a good comparison of the weather in Oregon and Virginia will be limited based on the available information.
1)Weather charts for different months: Martin is looking at a weather chart for Oregon in November and a weather chart for Virginia in April.
Since these charts represent different months, it's important to note that weather patterns can vary significantly between different seasons.
November in Oregon may have different weather conditions compared to April in Virginia.
Therefore, comparing these charts directly may not provide an accurate representation of the overall weather differences between the two states.
2)Precipitation map for Oregon in July: While Martin has a precipitation map for Oregon in July, this data does not align with the weather charts for November in Oregon and April in Virginia.
Comparing precipitation levels in July for Oregon with weather conditions in different months for Virginia would not yield a meaningful comparison.
3)Temperature map for Virginia in July: Similarly, the temperature map for Virginia in July does not correspond to the weather charts for November in Oregon and April in Virginia.
July temperatures in Virginia may differ from those in April, and comparing them to the November weather in Oregon would not provide a relevant comparison.
To make an accurate and meaningful comparison of the weather between Oregon and Virginia, it would be essential for Martin to gather data for the same months or similar timeframes.

QUESTION 1: Different Line Types Look at the drawing of a different bicycle pump below. This drawing is accurate, so we call it a scale draw It is four times smaller than a real pump. We say it is drawn to a scale of 1:4. That means that if you meas the length of the outer tube of this drawing, it will be four times smaller than the outer tube of the real pu F + 320 Figure 9: Bicycle pump. Scale 1:4 Why is the outer tube of this pump drawn with solid lines?
Answer:
The outer tube of the pump is drawn with solid lines because it represents the visible edges of the object, which are the most important and prominent features of the drawing. Solid lines are used to indicate visible edges, while other types of lines such as dashed or dotted lines are used for hidden or construction lines that are not meant to be seen in the final drawing.
Explanation:
When drawing an object, it's important to distinguish between the visible edges and the hidden or construction lines. The visible edges are the lines that represent the outer contour or silhouette of the object, which define its shape and form. In the case of the bicycle pump, the outer tube is the most prominent and recognizable feature of the pump, so it's drawn with solid lines to emphasize its importance and to make it stand out from the other parts of the pump.
On the other hand, the hidden or construction lines are used to guide the drawing process, to show the internal structure or components of the object, or to indicate the position of other features that are not visible from the current viewpoint. These lines are usually drawn with dashed or dotted lines to distinguish them from the visible edges and to avoid confusion.
By using different types of lines, the artist can create a clear and accurate representation of the object, with all the relevant information conveyed in a concise and understandable way. This is especially important in technical or scientific drawings, where precision and clarity are essential for conveying complex ideas or designs.

Why is transverse unequal length wishbone preferred to that of equal length?
Answer:
It allows the wheels to move of the neutral position without the tires scrubbing
Explanation:
The double wishbone suspension is independent and it can be used in both the front wheels and it affords very good control of the outward or inward tilting of the front wheel and it keeps the wheels perpendicular to the road surface
However, when equal length parallel wishbone are installed, it gives rise to scrubbing of the tires as the wheels turn in the tracks
The development of unequal length non-parallel transverse or converging wishbones with A-arms suspension resolved the tire scrubbing effect on the wheels when moving out of the neutral position.
Which fields of engineering use fluid power? Explain how these fields make use of fluid power systems: water supply, agricultural equipment, construction, and earth-moving equipment.
Answer:
Some fields of engineering that use fluid power are construction, heavy equipment, metallurgy, manufacturing, and oil and gas.
Water supply systems consist of these hydraulic components:
Pipes: Pipes transport water around the system. They are primary feeders (large-diameter pipes), secondary feeders (medium-diameter pipes), and distributors (small-diameter pipes).
Valves: They control the direction of the water flow. Indicating valves convey whether they are open or closed and non-indicating valves do not.
Hydrants: Hydrants appear at periodic intervals along the underground pipe network to provide water for firefighting.
Storage containers: Tanks located at a height provide water when demand is higher than supply. Gravity provides the required water pressure. Pumps can elevate water and refill the tank.
Agricultural equipment: Machines with hydraulic conveyors help transport harvested crops to wagon trailers.
In the construction industry, industrial forklifts lift and transport heavy weights. Hydraulic cylinders can tilt, lower, or elevate the required weight in a smooth motion.
Earth-moving equipment such as excavators have hydraulically powered buckets that can dig up ground, carry soil in the bucket, and drop the soil into trucks.
