storage Tank A to another storage Tank B, which has a storage
capacity of 250 m3 , 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.
Q1. 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 (L/s) 0 2 4 6 8 Discharge pressure (m) 120 115 107 96 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=kQ2 + c Density of water(Pwater) = 1000 kg/m², g=9.81 m/s Tank B 250m 79m dia. 100 Tank A Figure Q1
