Calculate the average power in kW that can be generated in a hydro-electric project from the following data
• Catchment area = 5 x 109 m2 ; Mean head, H = 30 m
• Annual rainfall, F =1.25 m ; Yield factor, K = 80 %
•Overall efficiency, noveall= 70%
If the load factor is 40%, what is the rating of generators installed?
