Air flows through a horizontal pipe of constant diameter, but there is a build-up of debris halfway down the pipe that the blocks a section of the flow area. The air enters the pipe at 320 K, 900 kPa, and a velocity of 30 m/s. The exit of the pipe is clear of debris and the flow area is the same as that of the inlet. The air exits the pipe at 305 K. For the air exiting the pipe, determine:
