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) 

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)
