The sump pump has a net mass of 310 kg and pumps fresh water against a 6-m head at the rate of 0.125 m³/s. Determine the vertical force R between the supporting base and the pump flange at A during operation. The mass of water in the pump may be taken as the equivalent of a 200-mm-diameter column 6 m in height.
