## The area under daily load curve divided by 24 gives

The area under daily load curve divided by 24 gives:

- Demand factor
- Maximum demand
- Connected load
- Average load for day

Correct answer: 4. Average load for day

## A large hydropower station has head of 350 m and an average flow of 1400 m³/s

A large hydropower station has head of 350 m and an average flow of 1400 m³/s. The reservoir is composed of series of lakes covering an area of 6400 km². The available hydraulic power is:

- 3452 MW
- 3902 MW
- 4352 MW
- 4802 MW

Correct answer: 4. 4802 MW

Solution:

Hydraulic power available is given by: P = 9.8 QH kW = 9.8 * 1400 * 350 = 4802 * 10^6 W = 4802 MW

## Condensers in power plants are used for condensing

Condensers in power plants are used for condensing:

- Water to ice
- Steam to water
- Hydrogen to liquid gas
- None of these

Correct answer: 2. Steam to water

## If load factor of a power plant increases, the cost of power generation per unit will

If load factor of a power plant increases, the cost of power generation per unit will:

- Increase
- Remain the same
- Decrease
- None of these

Correct answer: 3. Decrease

## Fuel transportation cost is the least consideration for

Fuel transportation cost is the least consideration for:

- Diesel power plants
- Nuclear power plants
- Hydroelectric power plants
- Steam power plants

Correct answer: 3. Hydroelectric power plants
