(20 pts) The enthalpy change associated with heating 150 L/min of air from 45°C to 125°C is 885 cal/mol. Calculate the heat required (in kW) for a steady-state process where air is heated according to these conditions (e.g., a heater unit with one inlet and one outlet). You can assume the air behaves as an ideal gas, and that kinetic and potential energy changes are negligible.
