1. What is a Torque from Pressure Calculator?

Definition: This calculator determines the torque generated by a given pressure acting on a specific area at a certain radius.

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

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 acting on an area creates a force, and this force applied at a radius from the rotation axis generates torque.

3. Importance of Torque Calculation

Details: Accurate torque calculation is essential for designing mechanical systems, selecting appropriate motors, and ensuring system safety.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What are typical pressure values in hydraulic systems?
A: Common hydraulic systems operate between 1-35 MPa (1,000,000-35,000,000 Pa).

Q2: How does radius affect torque?
A: Torque increases linearly with radius - doubling the radius doubles the torque for the same force.

Q3: Can I use this for pneumatic systems?
A: Yes, the same formula applies to any system where pressure acts on an area to create rotational force.

Q4: What if my pressure is in psi?
A: Convert psi to Pascals first (1 psi ≈ 6894.76 Pa).

Q5: Does this account for efficiency losses?
A: No, this calculates theoretical torque. Actual torque may be lower due to friction and other losses.
