The manager of an amusement park at the bottom of Niagara Falls wants to install a water turbine to produce 100 kW.  (assumed to be incompressible) would enter the pipeline leading to the turbine at 20°C and 0.10135MPa at the top of the falls, 51m above the turbine exit, with a velocity of 3 m/s. The water should leave the turbine at 20°C and 0.10135 MPa. Assume the pipeline and the turbine are both adiabatic.

A. Determine the mass flow rate of the water in kg/min.

B. Determine the diameter of the pipeline
