Air enters an 8” diameter pipe at atmospheric pressure at a velocity of 30 ft/s and 65 F and exits at approximately the same pressure. While in the pipe, the air passes over a heat exchanger that causes its temperature to increase by 25 F. Determine the following for the air:
The mass flow rate of the air (in lbm/s)
The exit velocity of the air (ft/s)
