No-production air leakage fraction calculator

A no-production load/unload test estimates leakage capacity fraction when test conditions suit the method.

L_{\text{pct}} = \frac{t_{\text{load}}}{t_{\text{load}} + t_{\text{unload}}} \times 100

Calculator

Enter the values you know and leave one box empty. Calculate finds the empty one, the result or any input.

Given

L_{\text{pct}} = \frac{2}{2 + 8} \times 100 = 20

Symbol	Meaning	Unit
$L_{\text{pct}}$	estimated leakage fraction of compressor capacity	%
$t_{\text{load}}$	loaded time during a no-production test	min
$t_{\text{unload}}$	unloaded time during the same test	min

Results are estimates for study and screening. Check the inputs, units and assumptions before you use them for design, billing or contract decisions.
