Hot oil at 110 ℃ heats water from 30 ℃ to 70 ℃ in a counter-current double-pipe
heat exchanger.
The flow rates of water and oil are 50 kg min−1 and 100 kg min−1, respectively,
and their specific heat capacities are 4.2 kJ kg−1 ℃−1 and
2.0 kJ kg−1 ℃−1, respectively.
Assume the heat exchanger is at steady state.
If the overall heat transfer coefficient is 200 W m−2 ℃−1,
the heat transfer area in m2 is __________
Correct : a
