Question

a m 41. Water that falls from a waterfall is used to gener- ate electricity. If the height of water fall is 100 m and 102 m3 of water falls every minute, then find the hydel energy in MWh generated in one day. Assume that 60% of the energy of the flowing water is converted into electricity. (Take density of water as 1000 kg m-3).​

Answer 1

Answer:

Given,

h=60m

tm=15kg/s

g=10m/s2

Loss due to friction force is 10%, only 90% input is used to generate power,

P=ghtm×10090

P=10×60×15×0.9

P=8.1kW
