How much water can be pulled with a lift of 20 feet at 60% efficiency?

To determine how much water can be pulled with a lift of 20 feet at 60% efficiency, we need to involve some calculations based on hydraulic principles.

First, we establish the theoretical flow from a pump. For a lift of 20 feet, we can use the formula that relates the vertical lift, pump efficiency, and the potential flow rate. The efficiency of a pump indicates how effectively it converts the energy used into hydraulic power; therefore, at 60% efficiency, the ability to lift water is reduced accordingly.

The formula for the flow rate in gallons per minute (GPM) often stems from calculations involving physical properties such as water weight, lift, and pump capacity. Water has a weight of approximately 8.33 pounds per gallon. A lift of 20 feet essentially means that, theoretically, for every cubic foot of water lifted, a specific amount of energy is required, accounting for inefficiencies in the system.

At 60% operational efficiency, you're only able to achieve 60% of the theoretical flow rate. If we consider operations that typically yield around a higher theoretical GPM flow but only achieve proportionately less due to losses, calculations would reflect a feasible output around 300 GPM for a 20-foot lift at
