In a condenser of a steam power plant, the lake water is used as a coolant for the condensing steam. Steam enters at 10 kPa and 100 degrees Celcius and leaves as saturated liquid at 10 kPa. The mass flow rate is 500 kg/min/. The magnitude of heat transfer (in kW) from the condensing steam to the coolant water, assuming no heat tranfer from the condenser shell to the surrounding, is?
Coolant in lake water: 20 degrees celsius, 100 kPa, 200 kg/sec
water coolant out: 100kPa.
