Explain what the process is for installing and removing a sheet pile retaining wall system. What are some of the benefits and limitations of this system?

Denitrification is commonly accomplished as a separate process after carbonaceous BOD removal. An alternative is to recycle mixed liquor to an anaerobic stage at the head end of the aeration tank. What potential advantage does the alternative offer? Explain.

introduction about Types of Parking and parking regulations

(a) What is the chemical form of most nitrogen as it arrives at a wastewater treatment plant? (b) What are the main chemical forms of nitrogen relevant to wastewater and its treatment? Show these in a simple nitrogen cycle.

you are a client asked an architect to design a villa for yourself. You as a client didn’t ask for fees. The architect finished design and tried to collect the fees, and you were reasonable thinking that the fees will be around $3000. Since, this was paid for similar villa design of your friend. The architect argued that the fees should be $5000, discuss the possible action by judge if architect sued you and explain why?     

The velocity field of a permanent, incompressible and isothermal flow is given by

u = a (x^2 - y^2)   (1)
v = −2axy   (2)
w = 0    (3)

Gravitational acceleration acts on the z axis only.

a) Write the Navier-Stokes equations for this flow, canceling the appropriate terms
and replacing the non-zero derivatives with their detailed expression. Be sure to indicate
clearly your assumptions. (4 points)

b) From the result obtained in (a), demonstrate that the pressure field is continuous and therefore
physically possible (2 points)

c) Get the expression for the flow pressure field (4 points)

Design a community drainage system for 20O people

2. In the Rational Method the peak runoff resulting from a rainfall event depends on which of the following factors

1. The frequency and duration of the rainfall event.
2. The size of the area on which the rainfall lands.
3. The characteristics of the surface over which the rainwater flows.
4. The time that has elapsed since the last rainfall event.

1. I, II, III and IV.
2. I, II and III only.
3. I and III only.
4. II and III only.

3. Which of the following are assumptions of the Rational Method?

1. Peak flow occurs when the entire watershed is contributing to the flow.
2. Rainfall intensity is the same over the entire drainage area.
3. Rainfall intensity is uniform over a time duration equal to the time of concentration.
4. Frequency of the computed peak flow is the same as that of the rainfall intensity.

1. I, II, III and IV.
2. I, II, and III only.
3. I and III only.
4. II and IV only.

Why did king Henry VIII of England break with the Roman Catholic Church? Make sure to also list and explain the legislations that were approved under Henry VIII by the English Parliament that officially split the Church of England from the Catholic Church. Under Henry, was the Church of England dramatically different from the Roman Catholic Church?
