A gas mixture at 675.0°C and 113 kPa absolute enters a heat exchanger at a rate of 69.0 m3/hr. The gas leaves the heat exchanger at 245.0°C. The change in enthalpy of the gas during the cooling process is -6.80 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.
Nitrogen gas at 300 K flows into a well-insulated device operating at steady-state. There is no power supply to this device. The device has two exit streams, 2/3 of the nitrogen (by mass) leaves at 400 K and 1 bar. The remainder of the nitrogen also ..
