A gas mixture at 400.0°C and 135 kPa absolute enters a heat exchanger at a rate of 70.0 m3/hr. The gas leaves the heat exchanger at 295.0°C. The change in enthalpy of the gas during the cooling process is -3.60 kJ/mol. What is the heat required in kW? Assume the gas behaves ideally and that the changes in kinetic and potential energy are negligible.
The question belongs to Chemical Engineering and it discusses about calculation of heat required in a heat exchanger.
