A compressor system which is controlled by starting-and-stopping is composed of a compressor with pumping capacity of 50 m³/min of free air and a receiver tank of 20 m3. The circuit demand is 25 m3/min of free air. No of start/stops is required to be 15 every hour. If the maximum line pressure is 8 bar gauge, what must be the low level pressure?

A centrifugal pump as shown in Figure below has a 100 mm diameter suction pipe and a 75 mm diameter delivery pipe. When discharging 15 L/s of water, the inlet water mercury manometer with one side exposed to the atmosphere recorded a vacuum deflection of 198 mm of Hg; the mercury level on the suction side was 100 mm below the pipe centerline. The delivery pressure gauge, 200 mm above the pump inlet, recorded a pressure of 94.666 Kpa. The measured input power was 3.2 kW. Calculate the pressure at the suction.
