3. In steam and gas turbines Casing contains controls for working fluids.
a) True
b) False

Explanation: In steam and gas turbines casing over turbine blades contains controls for working fluids.

4. When pressure drop is in stages then that turbine is called as ________
a) velocity compounded impulse turbine
b) pressure compounded impulse turbine
c) velocity compounded reaction turbine
d) none of the mentioned

Explanation: In pressure compounded impulse turbine pressure drop is in several stages and pressure loss is reduced.

5. Steam velocities in pressure compounding is ______
a) low
b) high
c) velocity has nothing to do with pressure compounding
d) none of the mentioned

Explanation: In pressure compounding the Conversion of kinetic energy in work is in several small stages and hence velocity of steam is low.

6. In parsons turbine to increase area between blades its height is to be ________
a) height has nothing to do with area between blades
b) decreased
c) increased
d) none of the mentioned

Explanation: In parsons turbine velocity is increased and as a result area between the blades is to be increased and it was increased by tapering the blade height.

7. If specific volume of steam increases its blade height _______
a) increases
b) decreases
c) not related with each other
d) none of the mentioned

Explanation: If the specific volume of steam increases its area need to be increased and hence its blade height is increased.

8. Blade entrance angle is measure for __________
d) none of the mentioned

9. Blade exit angle is a measure for _________
d) none of the mentioned

10. Nozzle exit angle is the measure of angle with which steam is leaving the nozzle.
a) True
b) False

Explanation: Nozzle exit angle is the angle with which steam exits the nozzle.
