Hydraulics formulas serve as the quantitative backbone of fluid power engineering, translating the behavior of pressurized liquids into predictable mechanical actions. Pascal’s Law dictates that pressure applied to a confined fluid is transmitted undiminished in all directions, forming the basis for hydraulic multiplication.

These formulas are critical for selecting motors and energy sources, as well as for diagnosing systems that are running hot or consuming excessive electricity. 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.
The relationship between flow velocity, pipe diameter, and volumetric flow is defined by the continuity equation, which ensures that fluid mass is conserved throughout the system. Neglecting this calculation results in excessive pressure drops, sluggish operation, and inefficient energy consumption due to turbulence or friction losses.

Pascal's Law and Pressure Transmission The formula $P = F / A$ (Pressure equals Force divided by Area) is the cornerstone of hydraulic analysis. 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).
