Water from a reservoir passes over a dam through a turbine and discharges from a 70-cm ID pipe at a point 65m below the reservoir surface. The turbine delivers 0.80MW. 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 2m3/s.)
