A pump draws water from a reservoir and delivers it at a steady rate

A pump draws water from a reservoir and delivers it at a steady rate of 115 L ·s−1 to a tank in which for free surface level is 12 m higher than that in the reservoir. The pipe system consists of 30 m of 225 mm diameter pipe (f = 0.007) and 100 m of 150 mm diameter pipe (f = 0.008) arranged in series. Determine the flow rate 2 s after a failure of the power supply to the pump, assuming that the pump stops instantaneously. Neglect minor losses in the pipes and in the pump, and assume an incompressible fluid in rigid pipes with f independent of Reynolds number.
