Question

Find the power available if overall efficiency of plant is 80%, flow rate is 4.42cumecs and head 400m?

(a) 6.52MW

(b) 8.18MW

(c) 11.255MW

(d) 13.875MW

I had been asked this question in my homework.

I want to ask this question from Hydrographs topic in chapter Hydro Electric Power Plant of Energy Engineering

Answer 1

Right choice is (d) 13.875MW

For explanation I would say: Power available:

    P = wQHno X 10^-3 KW

        = 9810 X 4.42 X 400 X 0.8 X 10^-6 MW

     P = 13.875MW.
