How do you calculate the torque of a hydraulic motor?
Hydraulic Pump Motor Sizing
- Flow rate. Q = D n / 1000 (1) where. Q = flow rate (l/min) D = displacement of piston (cm3/rev)
- Shaft Torque. T = D p / 20 π (2) where. T = torque (Nm) p = pressure (bar)
- Shaft Power. Ps = T n / 9554 (3) where. Ps = shaft power (kW)
- Hydraulic Power. Ph = Q p / 600 (4) where. Ph = hydraulic power (kW)
How do you calculate fluid torque?
Torque = Pressure (PSIG) × Pump Displacement (CIPR) / 2?
What is the formula used to calculate horsepower in a hydraulic system?
HHP=P*Q/1714
It is commonly calculated with the equation HHP=P*Q/1714, where P stands for pressure in pounds per square in., Q stands for flow rate in gallons per minute, and 1714 is a conversion factor necessary to yield HHP in terms of horsepower.
What is r in the torque equation?
The magnitude τ of the torque is given by. where r is the distance from the axis of rotation to the particle, F is the magnitude of the force applied, and θ is the angle between the position and force vectors.
What is the formula to calculate hydraulic pump displacement?

Hydraulic Pump Formulas
| Formula For: | Word Formula: |
|---|---|
| PUMP DISPLACEMENT IN CUBIC INCHES/REVOLUTION | DISPLACEMENT = FLOW RATE(GPM) x 231 PUMP RPM |
| PUMP TORQUE IN INCH POUNDS | TORQUE = HORSEPOWER x 63025 RPM |
| PUMP TORQUE IN INCH POUNDS | TORQUE = PRESSURE(PSIG) x PUMP DISPLACEMENT(CIPR) 2 x 3.14 |
How do you calculate the hydraulic power of a pump?
Hydraulic power is defined as flow multiplied by pressure. The hydraulic power supplied by a pump is: Power = (P x Q) ÷ 600 – where power is in kilowatts [kW], P is the pressure in bars, and Q is the flow in litres per minute.
How do you calculate hydraulic horsepower?
To find hydraulic horsepower, use the equation: HP = (PSI X GPM) / 1714. PSI = Pressure in Pounds per Square Inch. GPM = Flow Rate in Gallons per Minute. Example: Calculate hydraulic horsepower when pressure. is 2000psi and flow rate is 20GPM: Horsepower = (2000 x 20) / 1714.
How to calculate the amount of torque needed?
Method 2 of 3: Figuring out the Torque for Angled Forces Start with the distance of the radial vector. The radial vector is the line that extends from the axis or point of rotation. Work out the amount of force being applied. In most torque problems, this value will also be given to you. Measure the angle made by the force vector and the radial vector. Use your calculator to find the sine of the angle θ.
How do we calculate torque?
Torque Calculation. A practical way to calculate the magnitude of the torque is to first determine the lever arm and then multiply it times the applied force. The lever arm is the perpendicular distance from the axis of rotation to the line of action of the force.
How do you calculate rpm?
A three-phase induction motor’s RPM can be calculated using a relatively simple mathematical formula. RPM is equal to (120 x frequency)/number of poles in the motor. Take the necessary measurements Find the frequency of the motor in hertz. Most commercial motor operate at between 50 and 60 hertz.
