Forchheimer equation is used to define the flow at higher velocities. DeltaP/L =av+bv2. The equation describes the losses due to both viscous and inertia drags. The linear term is similar to that of Darcy's equation (viscous drag) and the quadratic term is the loss due to inertia drag.

AUX gas reading problem on QE with full MS and PRM method in one run?

Dear QE-users, In the method where full MS positive mode and PRM mode are used, we always get an incorrect auxiliary gas reading (41 instead of 25). This only happens in this method; other...
