1. In a uniform open channel flow:
   1. The total energy remains constant along the channel
   2. The total energy line either rises or falls along the channel depending on the state of the flow
   3. The specific energy decreases along the channel
   4. The line representing the total energy is parallel to the bed of the channel

2. In which of the following situations, the flow is uniform?
   1. Flow in channel contraction or expansion
   2. Flow in the vicinity of a bridge pier
   3. Flow at the middle of a long prismatic channel far away from the obstruction

3. Uniform flow in an open channel exists when the flow is steady, and the channel is
   1. Prismatic
   2. Non-prismatic and the depth of the flow is constant along the channel
   3. Prismatic and the depth of the flow is constant along the channel
   4. Frictionless

4. In uniform flow, there is a balance between:
   1. Gravity and frictional forces
   2. Gravity and inertial forces
   3. Inertial and frictional forces
   4. Inertial and viscous forces

5. The water depth in a wide channel is equal to 1.2m (For a very wide channel R is approximately equal to y). If the Chezy coefficient is equal to 49 (metric), then Manning coefficient n (metric) is equal to:
   1. 0.024
   2. 0.021
   3. 0.026

1. Suppose an office building is constructed for an owner. The punch list items are addressed, and the project is accepted by the owner. Three months later during the winter season, the owner noticed that the roof developed a small leak and that the leaking water caused discoloration of several suspended ceiling tiles. The main cause of the leakage is an issue in the roof installation and structure that was not readialy observable during final inspection carried out by the owner’s representative. Suppose the owner then noticed that the space between the bottom of three doors and the surface of the floor was nearly ½ inch, exceeding the ¼ inch that was specified in the construction documents. (1) What type of defect is the roof issue? Should the roof repairs and the replacement of the ceiling tiles be covered by warranty? Explain your answer. (2) What type of defect is the extra space between the bottom of doors and the surface of the floor? Should the repaid of the space between the bottom of doors and the surface of the floor be covered by warranty? Explain your answer.    

A cubical tank has sides of 4.5m which contains three immiscible liquids at same depths. A water upto a height of 1.5m above the base, An immiscible liquid of specific gravity 0.9 is filled in between both liquids (mid-portion) upto 1.5m height, the upper remaining part is filled with oil of specific gravity 0.79. Calculate (i) The value of pressures at the top, at the interface points and at bottom on one side of the tank (ii) The position of center of pressure for one side of the tank. (iii) What suggestions would you give to your client on the basis of obtained results? (iv) Pressure distribution Diagram
