A centrifugal pump is being tested for performance and during the test the pressure reading in the 0.305-m-diameter suction (inlet) line just adjacent to the pump casing is -20.7 kPa (vacuum below atmospheric pressure). In the discharge (outlet) line with a diameter of 0.254 m at a point 2.53 m above the suction line, the pressure is 289.6 kPa gage. The flow of water from the pump is measured as 0.1133m3/s. (The density and viscosity of water are measured at +4C)
