Question 38
CHMCQ2 marksNeeds review
Hot oil at 110 °C heats water from 30 °C to 70 °C in a counter-current double-pipe heat exchanger. The flow rates of water and oil are 50 kg min
and 100 kg min
, respectively and their specific heat capacities are 4.2 kJ kg
°C
and 2.0 kJ kg
°C
, respectively. Assume the heat exchanger is at steady state. If the overall heat transfer coefficient is 200 W m
°C
, the heat transfer area in m
isYour answerChoose one option.
