19.24 kPa

39.24 kPa

29.24 kPa

49.24 kPa

Solution:

For the automatic control scheme during fluid flow, which of the following instruments is used?

Pulley plates

Pitot Static Tube

Rotameters

Rotary Piston

Solution:

Surface tension at a fluid interface exists due to the action of

cohesive forces

adhesive forces

both cohesive forces and adhesive forces

neither cohesive forces nor adhesive forces

Solution:

Which of the following statements about Pelton wheel is not true?

It is a tangential flow impulse turbine.

It is a high head turbine.

It has high specific speed.

It is a low discharge turbine.

Solution:

For the laminar flow of oil with a maximum velocity of 2 m/s between two horizontal parallel plates which are 10 cm apart, determine the pressure gradient.

5246 N/m²

4563 N/m²

-7289 N/m²

-3924 N/m²

Solution:

What is the correct relation between the maximum velocity (V_max) and the average velocity (V) in the flow between parallel stationary plates?

None of the above

V_max = (3/2) * V

V_max = 2 * V

V_max = V, and the velocity is constant

Solution:

Which of the following options is correct about the U-tube manometer?

is used upright if pressure differential is small

is used inverted if pressure differential is small

cannot be used to measure the absolute pressure of a fluid

cannot be inclined at any angle

Solution:

Which of the following definitions is correct for fluid kinematics?

the study of fluid at rest or in motion with or without the consideration of forces

the study of fluid in motion without consideration of forces

the study of fluid at rest

the study of fluid in motion considering the application of forces.

Solution:

In a hydroelectric power plant, the dynamic pressure energy of the fluid is the sum of two energies: 'a' and 'b'. Which of the following correctly identifies 'a' and 'b'?

None of the Above

'a' = Pressure energy and 'b' = 0, or 'a' = 0 and 'b' = Pressure Energy

'a' = Kinetic Energy and 'b' = 0, or 'a' = 0 and 'b' = Kinetic Energy

'a' = Pressure Energy and 'b' = Kinetic Energy
