This calculator is used to calculate pressure decay leak test cycle times. To calculate, enter a known value into all but one field. Press the Calculate Button to solve for the open field.
The Ideal Gas Law: PV=nRT
Pressure Decay Leak Rate Formula
L R =(PC)(V)(60)/(T)(14.7)
LR= Leak Rate in sccm
PC= Pressure Change in PSI
V= Volume in cc (cubic centimeters)
T= Test Time in seconds
