A Super-heated Steam at 200°C and 2 atm with mass flow rate of 1000 kg/h is being cooled in a counter-current heat exchanger. The hot outlet stream should reach the bubble point. A cooling water stream is available at 15°C and the inlet cooling water flow rate is 8000 kg/h. a. Find the required area for this heat exchanger, if the overall heat transfer coefficient (U) is 400W/m².K. ANSWER: a. Adjust the inlet cooling water flow rate, if the outlet cooling water temperature should be limited to 30°C.

Transcribed Image Text:A Super-heated
Steam at 200°C and 2 atm with
mass flow rate of 1000 kg/h is being cooled in a
counter-current heat exchanger. The hot outlet
stream should reach the bubble point. A cooling
water stream is available at 15°C and the inlet
cooling water flow rate is 8000 kg/h.
a. Find the required area for this heat exchanger, if the
overall heat transfer coefficient (U) is 400W/m².K.
ANSWER:
a. Adjust the inlet cooling water flow rate, if the outlet
cooling water temperature should be limited to 30°C.
