5-7 Air enters a 28-cm diameter pipe steadily at 200 kPa and 20°C with a velocity of 5 m/s. Air is heated as it flows, and leaves the pipe at 180 kPa and 40°C. Determine (a) the volume flow rate of air at the inlet, (b) the mass flow rate of air, and (c) the velocity and volume flow rate at the exit. O 0.36 m^3/s, 6.94 m/s O 0.33 m^3/s, 5.84 m/s O None of the above O 0.36 m^3/s, 5.94 m/s O 0.38 m^3/s, 5.94 m/s
