A drum-type steam generator operates at 160 bars. 1260 kg/s of water goes down the downcomer,
subcooled. The downcomer and risers are all 12 m high. The average water-steam mixture density is 350 kg/m
3. The pressure losses in the downcomer 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.
