A stream of air at 77F and 1.2 atm absolute flowing at a rate of 200 ft/h
Question:
A stream of air at 77°F and 1.2 atm absolute flowing at a rate of 200 ft’/h is blown through ducts that pass through the interior of a large industrial motor. The air emerges at 500°F. Using tabulated specific enthalpy data, calculate the rate at which the air is removing heat generated by the motor. What assumption have you made about the pressure dependence of the specific enthalpy of air?
