WebDec 22, 2015 · C is the compliance of a volumetric space due to the resilience of gas compression (units are for example m^3/Pa). And R is the flow resistance (units are for example Pa/ (m^3/sec)^2 ). So if I'm understanding this correctly, I should solve for Q by doing Q 2 = Δ P R. And if I had a 140psi tank that I vented to a 120psi tank, then P = 20.
