- Tidal
Correct answer: 4. Tidal
b. The structure which protects the conduit of the dam against the abnormal pressure of water:
- Penstock
- Surge tank
- Reservoir
- Value house
Correct answer: 2. Surge tank
c. Statement: Open conduits in dams don’t require surge tanks.

g. At present _______________ is the largest source of power generation:
- Coal
- Nuclear
- Hydroelectric
- Solar
Correct answer: 1. Coal
h. The steam exiting the boiler of the plant is at ____________ and _____________:
- Low temperature, low pressure
- Low temperature, high pressure
- High temperature, high pressure
- High temperature, low pressure
Correct answer: 3. High temperature, high pressure
i. A two pole generator in 50 Hz grid should be turned at:
- 1500 RPM
- 3000 RPM
- 6000 RPM
- 9000 RPM
Correct answer: 1. 3000 RPM
Explanation: Speed = 120 * f / P
Speed = 120 * 50 / 2 = 3000 RPM

- Slower than
- Faster than
- At similar speed as
- None of these
Correct answer: 1. Slower than
