- Do I add the potential energy term?
I am quite familiar with the Ergun equation's formulation.
My question is, do I need to subtract the potential term ΔP/Δz = -ρg/gc after the Ergun equation's own ΔP/Δz , assuming that the fluid is to be pumped upward, from the bottom of the bed to the top of the bed? I was thinking it should be negative because the fluid is counteracting gravity (fluid is flowing upward), which means that the pressure drop is greater.
Thanks.
