A turbine which normally operates under a net head of 300 m

A turbine which normally operates under a net head of 300 m is supplied with water at 2.5 m3 ·s−1 through a pipe 1 m diameter and 1.6 m long for which f = 0.005. During a test on the turbine governor the flow to the turbine is gradually stopped over an interval of 8 s, the retardation of the water being proportional to t5/4, where t represents the time measured from the beginning of the shut-down. Neglecting minor losses and assuming an incompressible fluid in a rigid pipe with f independent of Reynolds number, determine the head at the turbine inlet and the velocity in the pipe at t = 6 s.
