Frequently Asked Questions
What does this calculator calculate?
The Hydraulic Cylinder Fluid Power Calculator estimates Fluid Power based on the input parameters you provide
Why is system pressure important in this calculation?
system pressure is directly proportional to fluid power. When you enter system pressure in Pa, the calculator uses it in the engineering formula to compute the output
How should I interpret the result fluid power?
The calculator outputs fluid power in W. For larger power values, divide by 1000 to express the result in kW, or by 745.7 for horsepower. The result is computed directly from the input values using the defined engineering formula
What units should I use for the inputs?
Enter each value in the units shown next to the input field: System Pressure (Pa), Cylinder Bore Diameter (m), Piston Velocity (m/s), Stroke Length (m), Fluid Density (kg/m³), Dynamic Viscosity (Pa·s), Temperature (K). Make sure all inputs use the specified units for consistent results
What assumptions does this calculator use?
This calculator uses automatically validated engineering formulas. Results are approximate and should be validated against site-specific conditions, applicable codes, and professional engineering judgment
