Problem-1 Water is pumped from the large tank through a uniform diameter pipe (d = 3 in.) and exits as a free jet (refer figure-a). The plot of the flowrate (Q) versus pump-head (hp) is a straight-line graph that passes through points (3, 16) as shown in figure-b. If the pipe friction head loss is, h = 7V:/2g, where V is the average fluid velocity in the pipe, find a) the equation that relates hp and Q; b) flowrate and c) If the pump is 75% efficient, what horsepower is needed to drive it? Assume steady, incompressible flow. Ignore kinetic energy correction factor (a).
