A centrifugal pump is required to pump water to an open water tank situated 4 km away from the location of the pump through a pipe of diameter 0.2m having Darcy’s friction factor for 0.01. The average speed of water in the pipe is 2 m/s. If it is to maintain a constant head of 5 m in the tank, neglecting other minor losses, the absolute discharge pressure at the pump exist is
(a) 0.449 bar (b) 5.503 bar
(c) 44.911 bar (d) 55.203 bar
