How is hydraulic power calculated?

Hydraulic power is calculated using the formula ( P = Q \times \Delta P ). In this context, ( P ) represents the hydraulic power, ( Q ) is the flow rate (typically measured in liters per minute or gallons per minute), and ( \Delta P ) is the pressure differential (measured in Pascals or psi).

This equation is derived from the principle that power is the product of flow and pressure. Specifically, hydraulic systems operate by moving fluid through a system against a pressure, which can be utilized to perform work, such as lifting or moving loads. The flow rate indicates how much fluid is being moved, while the pressure differential represents the energy available in the hydraulic system to perform that work. Hence, multiplying these two variables gives a measure of the work done per unit time, which is the power output of the hydraulic system.

In other formulations, the flow rate and pressure could be related differently, but only this formulation directly correlates to how hydraulic systems are designed and assessed for performance in terms of power generation.
