Water from a reservoir passes over a dam through a turbine and discharges from a 70-cm id pipe at a point 55 m below the reservoir surface. the turbine delivers 0.80 mw. calculate the required flow rate of water in m3 /min if friction is neglected. (see example 7.7-3.) if friction were included, would a higher or lower flow rate be required? (note: the equation you will solve in this problem has multiple roots. find a solution less than 2 m3/s.)
