Air enters a 16-cm-diameter pipe steadily at 200 kPa and 20°C with a velocity of 5 m/s. Air is heated as it flows, and it leaves the pipe at 180 kPa and 40°C. The gas constant of air is 0.287 kPa·m^3/kg·K. Determine:
a. the volume flow rate of air at the inlet.
b. the mass flow rate of air.
c. the velocity and volume flow rate at the exit.
