Enter the pressure (psi), the area (in^2), and the radius (ft) into the calculator to determine the Torque From Pressure. 

Torque From Pressure Formula

The following formula is used to calculate the Torque From Pressure.

T = P*A*r
  • Where T is the Torque From Pressure (lb-ft)
  • P is the pressure (psi) 
  • A is the area (in^2) 
  • r is the radius (ft) 

To calculate torque from pressure, multiply the pressure by the area, then multiply by the radius.

How to Calculate Torque From Pressure?

The following example problems outline how to calculate the Torque From Pressure.

Example Problem #1

  1. First, determine the pressure (psi). In this example, the pressure (psi) is given as 100 .
  2. Next, determine the area (in^2). For this problem, the area (in^2) is given as  40 .
  3. Next, determine the radius (ft). In this case, the radius (ft) is found to be 10.
  4. Finally, calculate the Torque From Pressure using the formula above: 

T = P*A*r

Inserting the values from above and solving yields: 

T = 100*40*10 = 40,000 (lb-ft)

Example Problem #2

Using the same method as above, determine the variables required by the equation. For this example problem, these are provided as:

pressure (psi) = 30

area (in^2) = 15

radius (ft) = 20

Enter these given values yields: 

T = P*A*r = 9000 (lb-ft)
