several calculations outside of the laboratory. The group first operated the pump at a motor speed of 1750 rpm. The position of the control valve of the pump system was adjust using the computer control system at openings of 0, 20, 40, 50, 60, 80, and 100% flow. At each of the selected control points the following data was recorded: pump discharge and inlet pressures, flow rate measured by the orifice plate of the control system, flow rate determined by gravimetric measurement, rpm and torque of the…
