4. A pump is tested in the laboratory and the following data were obtained. Torque = T= 6.78 Nm Rotational speed = w = 20 Hz Inlet pressure = Pi = 68.95 kPa Outlet pressure = p2 = 193 kPa Velocity in the inlet line = V= 2.44 m/s Height to inlet gauge z1 = 0.61 m Height to outlet gauge = 22 = 1.52 m Inlet flow line = 2- nominal schedule 40
