As shown in the picture, air flows through a pipe. Heat is supplied to the airflow. The air at the inlet is 200kPa and 20 C with flow velocity of 5m/s. The exiting air is 180 kPa and 40 °C. The diameter of the pipe is 0.28 m. Determine (a) the volume flow rate of air at the inlet and outlet, and (b) the air velocity at the exit
