b)
Calculate the power consumption and the steady discharge of water
between the reservoirs in the pipeline system shown in Figure 4.1. The
static lift of the system is 15 m and the pipeline has diameter of 300 mm
and 500 m in length with a friction factor A = 0.004. Head losses in the
system include friction loss and minor head losses totalling 10V²/2g.
Assume the efficiency at the duty point is equal to 38%.
