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.
Answers
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

Technician a says that when more air is entering a spray booth than is removed it is considered to have negative pressure technician b say the negative air pressure draws more overspray through spray booth filters than positive air pressure Who’s right
Answers
In a spray booth, when the amount of air entering the booth is greater than the amount of air being removed, it is considered to have positive pressure. Conversely, when the amount of air being removed is greater than the amount of air entering, it is considered to have negative pressure. Therefore, Technician A's statement is incorrect.
On the other hand, Technician B's statement is correct. Negative air pressure can draw more overspray through spray booth filters because it creates a vacuum effect that draws in the overspray and helps prevent it from escaping into the rest of the work area. This is why spray booths are designed to have a negative pressure differential to help control overspray and keep the work environment safe.
Technician A is correct in stating that when more air is entering the spray booth than is being removed, it is considered to have negative pressure. Negative pressure means that the pressure inside the spray booth is lower than the pressure outside. This setup helps to contain the overspray and fumes within the booth, minimizing the risk of spreading them to the surrounding areas.
Technician B is also correct in stating that negative air pressure draws more overspray through the spray booth filters than positive air pressure. When the spray booth has negative pressure, it creates a suction effect. This suction draws the overspray particles towards the filters, improving their efficiency in capturing and removing the overspray from the air.
In summary, both technicians are correct in their statements. The negative pressure in the spray booth helps contain the overspray, and it also enhances the effectiveness of the booth's filters in capturing the overspray particles.

What are 5 tactics that can reduce the likelihood of injury?
Answers
Don't start any exercise program without first checking with your primary care provider. Your doctor can determine whether you're healthy enough to exercise, and what, if any, modifications you'll need to make to your program. "Exercise programs should be customized to the individual whenever possible to account for any limitations and ongoing medical conditions," Dr. Berkson advises.
2 Choose your workout carefully
High-impact exercise programs aren't ideal for women with conditions like arthritis or osteoporosis. Non-impact exercises, including swimming or using an elliptical exercise machine, will give you aerobic conditioning without stressing your joints.
3 Learn the proper technique
Don't start any new exercise without first learning the correct form. On the right is an example of proper squat technique. To learn the right form, work with a trainer at home or in the gym, or consult a physical therapist to help you tailor a workout to your health conditions and physical capabilities.
4 Get the right gear
Buy a pair of sturdy, comfortable sneakers that provide good arch support and have a cushioned heel to absorb shock. Wear loose, comfortable clothing that gives you room to move and breathe.
5 Start gradually
Don't jump into a new exercise program. "The greatest risk of injury comes with changing an exercise program or adding a new exercise," Dr. Berkson says. Start slowly. If you're cycling, for example, set the bike's controls on the lowest speed and tension, and pedal for just a few minutes your first few times. Gradually increase the speed and intensity only when you feel ready.

What is a Capacitor?A capacitor is an electronic component that stores electrical energy in an electric field. It is typically made up of two conductive plates separated by a non-conductive material, or dielectric.
When a voltage is applied across the plates, an electric field is created between them, which causes a build-up of electric charge on the plates. The amount of charge that can be stored on the plates depends on the capacitance of the capacitor, which is determined by the size and spacing of the plates, as well as the type of dielectric material used.

Answers
Answer:
Dear [Boss],
I am writing to recommend that our firm pursue a future in designing high-end alternative housing solutions. There is a growing demand for cutting-edge, sustainable housing options, and I believe our firm is well-positioned to meet this demand.
One area of opportunity is the use of recycled and reused materials in these builds. By incorporating materials such as reclaimed wood, recycled steel, and repurposed bricks, we can not only reduce our environmental impact, but also differentiate ourselves from other housing developers.
There are, of course, challenges to using these types of materials. They may require more time and effort to source, and there may be additional costs associated with their use. However, I believe the benefits of using recycled and reused materials far outweigh these challenges. Not only do they reduce waste and decrease our carbon footprint, they also have the potential to add unique character and value to our projects.
In terms of how to move forward, I recommend that we begin by researching and identifying specific recycled and reused materials that align with our design aesthetic and can be incorporated into our projects. We can also consider partnering with organizations or suppliers that specialize in these types of materials.
Overall, I believe that designing high-end alternative housing solutions using recycled and reused materials is a viable and exciting opportunity for our firm. By embracing this trend, we can not only meet the needs of an increasingly environmentally-conscious market, but also differentiate ourselves in a crowded industry.
Sincerely,

How would you design a wheelchair for wheelchair-using basketball players? Would you make it more or less massive?
Answers
The way i would design a wheelchair to be used by basketballers is;
I would make the wheel chair less massive so that it can be easy to control which in turn would not make his speed slower and also which will not reduce his agility.
In playing basketball, some of the key skills are;
1) Dribbling.
2) Shooting.
3) Defense.
4) Rebounding.
5) Passing.
While some of the key physical traits are;
1) Speed
2) Agility
3) Core strength
4) Leap ability
Now, if we have to make a wheel chair, we have to consider those skills and traits above.
Thus, the wheel chair would have to be less massive because if it is too massive it will be very hard for the person to control it and this will also affect his speed and agility which is ability to slide laterally or glide away from an opponent.
Thus, I would make the wheel chair less massive so that it can be easy to control which in turn would not make his speed slower and also which will not reduce his agility.
