## Thermal efficiency of steam power plant is around

Thermal efficiency of steam power plant is around:

1. 13.5%
2. 28%
3. 33.9%
4. 52%

## The overall efficient of steam power plant is ___________ its thermal efficiency

The overall efficiency of steam power plant is ___________ its thermal efficiency:

1. Same as
2. More than
3. Less than
4. None of above

## Diversity factor is always

Diversity factor is always:

1. Less than 1
2. Equal to 1
3. Greater than 1
4. None of these

Correct answer: 3. Greater than 1

Explanation:
Diversity factor is defined as the ratio of sum of maximum demands to maximum demand on the power station. Electric power station supplies power to loads of different types. The maximum demands of these loads donâ€™t occur at once, so, practically, the diversity factor is always greater than 1.

## Minimum quantity of fuel is required in

Minimum quantity of fuel is required in:

1. Steam power plant
2. Diesel power plant
3. Nuclear power plant
4. All above require equal value

Correct answer: 3. Nuclear power plant

## The peak power supplied by peak load station is

The peak power supplied by peak load station is:

1. Very cheap
2. Very costly
3. Same expensive as base load
4. None of these
