Power Generation MCQs Part 29

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

The area under daily load curve divided by 24 gives:

1. Demand factor
2. Maximum demand

## 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:

1. 3452 MW
2. 3902 MW
3. 4352 MW
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
