| Cylinder Force lbs.(Pounds of Force) |
Force=Pressure (psi) x Net Area (in²) |
F=PA |
| Fluid Motor Speed RPM (Revolutions per Minute) |
Speed = 231 x Flow Rate (GPM) F.M. Displacement (in³/rev.) |
n = 231 Q d |
| Fluid Pressure psi (Pounds per Square Inch) |
Pressure = Force (lbs) Area (in ²) |
P= F |
| Fluid Motor Torque lb-in (Inch Pounds) |
Torque = Pressure (psi) x F.M. Displacement (in³/rev.) 2π |
T= Pd 2π |
| Torque= Horsepower x 63025 RPM |
T = 63025 hp n |
|
| Torque = Flow Rate (GPM) x Pressure (psi) x 36.77 RPM |
T=36.77 Q P N |
|
| Fluid Motor Power hp (Horsepower) |
Horsepower = Torque (lbs-in) x RPM 63025 |
hp= Tn 63025 |
| Cylinder Area Extend in² (Square Inches) |
Area = π/(4 x Bore Diameter ²) | A = .7854 D² |
| Cylinder Area Retract (w/rod) in² (Square Inches) |
Area = (π/4 x Bore Diameter²) – (π/4 x Rod Diameter²) |
A= (.7854 Db²)– (.7854 Dr²) |
| Cylinder Volume G (Gallons of Fluid) |
Volume = Net Area (in²) x Stroke (in) 231 |
V = A L 231 |
| Cylinder Power hp (Horsepower) |
Horsepower = Pressure (psi) x Flow Rate (GPM) |
hp = P Q 1714 |
| Cylinder Velocity ft/s (Feet per Second) |
Velocity = 231 x Flow Rate (GPM) |
v= .3208 Q A |
|
Pump Outlet Flow |
Flow = RPM x Pump Displacement (in³/rev.) 231 | Q= nd 231 |
| Flow Rate Through Piping ft/s Velocity (Feet per Second) |
Velocity= .3208 x Flow Rate Through I.D. (GPM) |
v=.3208Q A |

The Risks of Unconnected Couplings
The Potential Danger of Using an Unconnected Coupling Portable hydraulic systems used for lifting, pushing, or pulling loads of several tons operate at pressures up to 10,000-psi (680 bar). Typically, they use portable hydraulic power units consisting of a hydraulic pump operated by manual, electric, or pneumatic power to actuate one or more rams —a […]
Cylinder Autopsy Reveals Failure Cause
Inside a Hydraulic Cylinder Failure A hydraulic repair facility in Australia recently shared an experience about a double-acting hydraulic cylinder that their customer said would extend, but not retract. When the cylinder came into the shop, the piston rod was almost completely retracted into the cylinder tube. Further inspection revealed the rod was stuck in […]
A Major Expense in Waste Collection
Why Hydraulic Costs are among the Top Expenses in Waste Collection When I worked as an editor for Hydraulics & Pneumatics magazine, I attended LOTS of trade shows. Sure, many of the exhibitors displayed hydraulic components, but my main reason for attending was to sniff out useful info from original equipment manufacturers. Because construction, mining, […]
