In the given system, water is carried from reservoir A to reservoir B with the use of a pump which works with 70% efficiency. If the discharge in pipe 1 is 80 l/s, find the power required to operate the pump. (For all pipes, the Manning's coefficient, n=0.01). (Use two significant figures for decimal fraction i.e. Answer will be 0.12) = = 60m Answer: A Pipe 1 4 = 3000 m D = 40 cm Pump Pipe 2 L. = 2000m D = 20 cm Pipe 3 Lg - 2500 71 D = 30 cm Pipe 4 L = 5000 m D = 50 cm B =100m
