## 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)}.

**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_{(inches}^{2}_{)} in inches square.

The equation of vacuum area can be writtern as,

VF_{(lbf)} = ( AP_{(psi)} – SP_{(psi)} ) * A_{(inches}^{2}_{)}

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_{(inches}^{2}_{)} = effective vaccum area in inches square

To calculate the vacuum force and ambient pressure 80psi and system pressure 2psi and vaccum area 10 inches^{2}.

Answer

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.

Answer

VF = ( AP – SP ) * A

780 = ( 80 – 2 ) * A

A = 10 inches^{2}.
