# Vacuum Force Calculator, Formula, Force Calculation

## Vacuum Force Calculator:

Enter the values of ambient pressure AP(psi) , system pressure Pounds SP(psi) & effective vaccum area  A (inches2) to determine the value of vacuum force VF(lbf).

 Enter Ambient Pressure: psi Enter System Pressure Pounds: psi Enter Effective Vaccum Area: inches2 Result – Vacuum Force: lbf

## Vacuum Force Formula:

The vacuum force VF(lbf) in lbf is equal to the ambient pressure AP(psi) in Pounds per square inch into subtracted by the system pressure SP(psi) Pounds per square inch to multiply the effective vaccum area A(inches2) in inches square.

The equation of vacuum area can be writtern as,

VF(lbf) = ( AP(psi) – SP(psi) ) * A(inches2)

Here,

VF(lbf)  =  vacuum force in lbf

AP(psi)  =  ambient pressure in Pounds per square inch

SP(psi)  =  system pressure Pounds per square inch

A(inches2)  =  effective vaccum area in inches square

To calculate the vacuum force and ambient pressure 80psi and system pressure 2psi and vaccum area 10 inches2.

VF = ( AP – SP ) * A

VF = ( 80 – 2 ) * 10

VF = 780 lbf.

To calculate vaccum area and the vacuum force 780 lbf  and ambient pressure 80psi and system pressure 2psi.
