Calculating System Power and Heat Dissipation The hydraulic power formula ($P_h$) is expressed as $P_h = (P \times Q) / 600$, where $P$ is pressure in bar and $Q$ is flow rate in LPM, resulting in kilowatts (kW). To determine the required electrical input, this value is divided by the pump efficiency (typically 85-92%).

Pascal's Law and Pressure Transmission The formula $P = F / A$ (Pressure equals Force divided by Area) is the cornerstone of hydraulic analysis. Mastery of these equations is essential for designing systems that lift, push, and control immense forces with precision.
While liquids are generally considered incompressible, under high pressures or rapid cycling, the slight compressibility of fluid can lead to phenomena like cavitation or delayed actuator response. The flow rate, typically measured in liters per minute (LPM) or gallons per minute (GPM), determines the speed at which actuators extend or retract.

Calculating the actual power required to drive a pump involves accounting for both the hydraulic power delivered to the actuator and the mechanical losses within the pump itself. This allows engineers to scale forces dramatically; for instance, a 100 Newton force on a 1 cm² piston can exert 10,000 Newtons on a 100 cm² piston, demonstrating the immense power of pressurized fluids.
