1. What is Torque from Pressure Calculator?

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

Purpose: It helps engineers and technicians determine the rotational force in mechanical systems where pressure is applied to a surface.

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 is multiplied by the area to get force, then multiplied by the radius to calculate torque.

3. Importance of Torque Calculation

Details: Accurate torque calculation is essential for designing mechanical systems, ensuring proper operation of rotating equipment, and preventing system failures.

4. Using the Calculator

Tips: Enter the pressure in Pascals, area in square meters, and 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 different units?
A: Yes, but you'll need to convert the result appropriately (1 Nm = 0.73756 ft-lb).

Q3: Where is this calculation commonly used?
A: In hydraulic systems, pneumatic systems, and any application where pressure creates rotational force.

Q4: Does the area shape affect the calculation?
A: No, the formula uses total effective area regardless of shape, as long as the radius is measured correctly.

Q5: How does radius affect torque?
A: Torque increases linearly with radius - doubling the radius doubles the torque for the same pressure and area.
