A drum type steam generator operate at 160 bars. 1260 kg of water goes down the downcomer 7.32 °C subcooled. The downcomer and risers are all 12 m high. The average water- steam mixture density in the risers is 350 kg/m³. The pressure losses in downcomers and risers total 0.5 bar. Calculate the power. In kwatts, needed to drive a forced circulation pump if pump efficiency is 0.70.

3- A drum type steam generator operate at 160 bars. 1260 kg of water goes down the
downcomer 7.32 °C subcooled. The downcomer and risers are all 12 m high. The average
water- steam mixture density in the risers is 350 kg/m³. The pressure losses in downcomers
and risers total 0.5 bar. Calculate the power. In kwatts, needed to drive a forced circulation
pump if pump efficiency is 0.70.
