The piston has a diameter of 150 mm and a stroke length of 300 mm. The pump is 1.9 m above the water level in the sump. Assume the atmospheric pressure to be 10.3 m of water, Fanning friction factor of 0.007, and the speed of the pump is 50 rpm. Determine the flow rate into or out of the air chamber when the crank makes an angle of 10°, 110°, and 170° with the inner dead center.
