1. What is a Torque from Pressure Calculator?

Definition: This calculator computes the torque generated by a given pressure acting over an area at a certain radius from the axis of rotation.

Purpose: It helps engineers and technicians determine rotational force in hydraulic systems, pneumatic systems, and mechanical designs.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( T \) — Torque (Newton-meters, Nm)
• \( P \) — Pressure (Pascals, Pa)
• \( A \) — Area (square meters, m²)
• \( r \) — Radius (meters, m)

Explanation: The pressure multiplied by the area gives the force, which when multiplied by the radius gives the torque about the axis.

3. Importance of Torque Calculation

Details: Accurate torque calculations are essential for designing rotating machinery, hydraulic motors, and ensuring proper system performance.

4. Using the Calculator

Tips: Enter the pressure in Pascals, the area in square meters, and the radius in meters. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for accurate results?
A: Use Pascals for pressure, square meters for area, and meters for radius to get torque in Newton-meters.

Q2: Can I use this for hydraulic motors?
A: Yes, this formula is fundamental for calculating hydraulic motor torque from system pressure.

Q3: How does radius affect torque?
A: Torque increases linearly with radius - doubling the radius doubles the torque for the same force.

Q4: What's the relationship between pressure and torque?
A: Torque is directly proportional to pressure - higher pressure means greater torque if area and radius remain constant.

Q5: Can this calculate brake torque?
A: Yes, it can calculate braking torque when pressure is applied to brake pads or shoes.
