Pressure Gradient Force Calculator, Formula, Pressure Calculation

Enter the values of IP(psi) , EP(psi) & A(inches2) to determine the value of pressure gradient force F(lb-f)

.

 Enter Internal Pressure: psi Enter External Pressure: psi Enter External Pressure: psi Result – Pressure Gradient Force: lb-f

The pressure gradient force F(lb-f) in lb-f is equal to the internal pressure IP(psi) in Pounds per square inch to subtracted by the external pressure EP(psi) Pounds per square inch and multiply the surface area A(inches2) in inches square.

The formula for pressure gradient force can be writtern as,

F(lb-f)  =  | IP(psi) –  EP(psi)  | *  A(inches2)

Here,

F(lb-f)  =  pressure gradient force in lb-f

IP(psi)  = internal pressure in Pounds per square inch

EP(psi)  = external pressure in  Pounds per square inch

A(inches2) = surface area in inches square

To find the pressure gradient force and internal pressure 45psi and external pressure 20psi and surface area 5inches2.

F = |IP – EP| * A

F = | 45 – 20 | * 5

F = 125N.

To find the surface area and  pressure gradient force 125N and internal pressure 45psi and external pressure 20psi.
