h = 10 m

Q = 50 m^3/s

n = 25%

g = 10 m/s^2

rho air = 1000 kg/m^3

m = rho × V

Ep × n = E listrik

m × g × h × n = P × t

rho × V × g × h × n = P × t

V/t = P/(rho × g × h × n)

Q = P/(rho × g × h × n)

P = Q × rho × g × h × n

P = 50 × 1000 × 10 × 10 × 25%

P = 1250000 watt

P = 1,25 Mwatt

jadi daya keluaran generator listrik tersebut adalah 1,25 Mwatt
