ESE 2022 CE Technical Quiz 11

Power loss in laminar flow through pipe is 

Statement (I): In an impulse turbine water impinges on turbine with kinetic energy

Statement (II): Impulse turbine works at atmospheric pressure.

A model having scale ratio of 1 : 40 is built for a rectangular weir over the river. The average depth of water in the river is 3.5 m. If the force acting on the model was calculated to be 3.0 N, the force acting on the prototype would be:

Match List-I (Type of hydraulic jump) with List-II (Froude’s number) and choose the correct option using codes given below:

A rectangular opening in a vertical side of tank has been provided opening is completely covered by plane plate hinged along horizontal centre line of the opening plate is kept in equilibrium in vertical position by a weight W as shown in figure. Value of W (in kN) would be (Neglect friction at hinge and pulley)

Velocity at point (2, 2) for the stream function would be :

Match List-I with List-II and choose the correct option using the codes given below

List-I

(Pollutant)

P. Nitrite

Q. Nitrate

R. Organic Ammonia

S. Free Ammonia

List-II

(Permissible limit, angle)

1. 0.15

2. zero

3. 45

4. 0.30

Codes:

Statement (I): Parshall flume is preferred over proportional weir as a velocity control device in a Grit chamber.

Statement (II): Head loss in Parshall flume is less than proportional weir.

Statement (I): If non carbonate hardness is present then carbonate hardness will be equal to alkalinity.

Statement (II): If non carbonate hardness is absent then carbonate hardness will be greater than alkalinity.
