    Flowrate through proportional control valve.

    Hi everyone, At our laboratory we are using two proportional valves of type 2836 to control a level control system. I would like to know the formula computing flow rate through those valves. Is the formula Q = K*u*sqrt(deltaP) correct? (where K is a constant, u is valve opening and delta P is...

    Does valve discharge coefficient vary?

    Hi, I am building a mathematical model for a two tanks system (as can be seen in the attachment)which can operate either as non-interacting (when h2 < H) or interacting system (when h2 > H). In order to do so I need to determine the discharge coefficient of the valve connecting two vessels B1...
