5. (15 points) A heat transfer unit is designed to use air at 150 C to activate an endothermic reaction. For this purpose, a pipe with ambient air at 25C is heated to 150 C. The change in specific enthalpy (AH) for this process is 3640 J/mol. If the outlet air at 150C leaves with a volumetric flow rate of 1.25 m /min and a pressure of 122 kPa, what is the heat (Q) required in kW? How much will it cost if the city of Tallahassee charges 0.03 cents per W? Assume ideal gas behavior and neglect changes otential and kinetic energy
