0.4 Air is heated from 25 C to 150 C prior to entering a combusion furnace. The change in specific enthalpy associated with this transition is 3640 J/mol and the heat requirement is 5.26 kW. The air pressure at the outlet point is 122 kPa absolute. Calculate the flow rate (m/min) of air at the heater outlet point, assuming ideal gas behavior and that kinetic and potential energy changes from the heater inlet to the outlet are negligible
