The pressure difference between upstream (1) and downstream (2) reservoir is defined as \(P_1 - P_2\).It is never possible for the flow to reverse and go from the downstream to the upstream reactor/reservoir through a line containing a Valve() object, which means that the flow rate is set to zero if \(P_1 < P_2\).. Valve() objects are often used between an upstream reactor and a …
