Known Cylinder

If the dimensions of a hydraulic cylinder are known, then numerous volumetric calculations can be carried out such as Full bore area and volumes. If the hydraulic system pressure is also known then the Thrust Force and Pull Force can also be determined. If the required cylinder speed is known then the Power required and Flow rates can also be calculated here.

Useful conversions factors:1kW = 1.34hp

1kW = 1.34hp

1bar = 14.5psi

1cm3 = 0.061 cu.inch

1cm2 = 0.155 in2

1Litre = 0.22 UK Gallons = 0.26 US Gallon

1kg = 2.2 lbs
