Question

Determine the capacity of hydro power plant to be used 10 hours peaking plant assuming daily flow in a river to be constant at 20m^3/s. and overall efficiency is 80%?

(a) 1.8835 MW

(b) 5.5 MW

(c) 3.25 MW

(d) 1.0 MW

The question was posed to me during an interview for a job.

Query is from Hydrographs in portion Hydro Electric Power Plant of Energy Engineering

Answer 1

Correct option is (a) 1.8835 MW

Explanation: Capacity of plant:

    P = wQHno X 10^-3 KW

    P = 9810 X 20 X 12 X 0.80 X 10^-6

       = 1.8835 MW.
