01 A centrifugal pump is used to deliver cold water from a water storage Tank A to another storage Tank B, which has a storage capacity of 250 m, by using a 100 mm diameter water pipe as shown in Figure Q1. The open end of the pump discharge pipe is located above the design water level in the storage water Tank B and at a height of 79 m above the water level in Tank A. The entire piping system has a resistance of 90 kPa at a flow rate of 4 L/S. The centrifugal pump operating at 2800 r.p.m. has the following characteristics : Flow rate (LIS) 0 2 4 6 8 Discharge pressure (m) 120 115 10796 79 Calculate the time required to fill up water tank B if the above pump is installed and operated at the design speed of 2800 r.p.m. (25 Marks) Given: H=kQ+C Density of water(Pwater) = 1000 kg/m', g=9.81 m/s? Tank B 250m 79m dia. 100 Tank A Figure Q1
