Determine the capacity of hydro power plant to be used 8 hours peaking plant assuming daily flow in a river to be constant at 65m^3/s. and overall efficiency is 80% and head 12m?(a) 6.1214 MW(b) 5.5 MW(c) 31.25 MW(d) 22.0 MWI got this question in a job interview.This intriguing question originated from Hydrographs topic in division Hydro Electric Power Plant of Energy Engineering

Answer» RIGHT choice is (a) 6.1214 MW

The explanation: CAPACITY of plant:

P = wQHno X 10^-3 KW

P = 9810 X 65 X 12 X 0.80 X 10^-6

= 6.1214MW.
