A hydroelectric power plant is to be built at a dam with a gross head of 200 m. The head losses in the head gate and penstock are estimated to be 6 m. The flow rate through the turbine is 18,000 L/min. The efficiencies of the turbine and the generator are 88 percent and 96 percent, respectively. The electricity production from this turbine is

(a) 6910 kW 

(b) 6750 kW 

(c) 6430 kW 

(d) 6170 kW

(e) 5890 kW
