Hello All,

this is my first thread here in this forum

honestly this is one of the best forums ever

my question is:

in the Outflow curve
There is a Pressure-drop like effect in the early times of the curve, am wondering if anyone can explain to me this effect?
what, why and how?

Genraly, pressure drops then reachs a point on the early times of the curve .. then start rising and keep on rising (which is the normal trend on the outflow curve)

can you please explain as soon as possible?
