Air enters a 36-cm diameter pipe steadily at 400 kPa and 40°C with a velocity of 8 m/s. Air is heated as it flows, and leaves the pipe at 250 kPa and 80°C. Determine (a) the volume flow rate of air at the inlet, (b) the mass flow rate of air, and (c) the velocity at the exit and (d) the volume flow rate at the exit. Take R of air as 0.287 kJ/kg K.
