To check the flow rate of a lift station pump rated at 225 gpm to determine its efficiency as compared to its rated capacity. The lift station has a diameter of 12 ft and is 20 ft deep. Without the pump running the influent flow to the lift station rises at a rate of 7 ft in 11 minutes and with the pump running the rise rate is 5 ft in 11 minutes. Calculate the rise rate in gpm with the pump running.
