In the system shown below in Figure 2, the ground levels at points A, B, and C are at the same elevation. The lift pumps at A provide flow at a discharge pressure of 400 kPa, the water level elevation in the elevated storage tank at C is 35 m, and the equivalent pipelines to the load centre at point B are as given in the illustration. Use the nomograph in the appendix.
(a) If this system is designed to supply the load centre with water demand of 7,430.4 m/d from the lift pumps and outflow from elevated storage when the water pressure at B equals 275 kPa, evaluate and justify the system discharge at B. [10 marks] (b) Design a water supply system for a discharge into elevated storage with no discharge at the load centre. Determine the equivalent pipe for the combined pipelines between A and C.
