Question
A hydro-electric station is operated with a
mean head (h) of 30 m and the water is
supplied from a lake which its dimentions
are 250 square km (area) and 125 cm
(depth), 70% of the water in this lake can
be utilized yearly to obtain the average
load. If the expected load factor for the
station is 80%. Calculate the power in kw
for which the station should be designed
(max. load). Assume that the mechanical
efficiency of the turbine is 90% and the
efficiency of the generato: is 95%
I hope that the solution is on an electronic
board or a white paper written by hand.
Thank you for your cooperation and good
.evening, sir
