Pressure-loss budget calculator

Set compressor pressure from end-use need plus measured losses, not complaints alone.

Units

p_{\text{end}} = p_{\text{supply,min}} - {\Delta p_{\text{components}}}

Calculator

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

Given

p_{\text{end}} = 112 - 17 = 95

Symbol	Meaning	Unit
$p_{\text{end}}$	minimum end-use pressure	psig
$p_{\text{supply,min}}$	minimum compressor operating pressure	psig
${\Delta p_{\text{components}}}$	component and piping drops	psid

Symbol	Meaning	Unit
$p_{\text{end}}$	minimum end-use pressure	kPa gauge
$p_{\text{supply,min}}$	minimum compressor operating pressure	kPa gauge
${\Delta p_{\text{components}}}$	component and piping drops	kPa

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