A drum-type steam generator operates at 160 bars. 1260 kg/s ofwater goes down the down comer, 7.32 C° sub cooled. The down comer and risers are all 12 m high. The average water-steam mixture density is 350 kg / m 3 . The pressure losses in the down comer and risers total 0.5 bars.

Calculate the power, in kilowatts, needed to drive a forced circulation pump if the pump efficiency is 0.70.
