A hydroelectric power plant takes in 30 m
/s of water through its turbine and discharges it to the atmosphere with
m/s. The total head loss in the turbine and penstock system is 20 m. (Assume turbulent flow with kinetic energy correction factor as 1.1. Density of water is 1000 kg/m
and acceleration due to gravity, g is 10 m/s
).The net head available to the turbine for power generation is --------------- m.
(rounded off to one decimal place).
