Minor Head Loss Coefficients for Valves
Minor Head Loss Coefficients for Valves
(OP)
Hello,
I am working on a problem where I'm trying to approximate the minor head loss in a scenario where one branch includes a mostly-closed globe valve. I say "mostly-closed" because there is an obstruction keeping the valve-seat from being fully engaged with the valve plate. I can't find any information that would give a good estimate of the minor head loss coefficient for that valve. I saw that a ball valve 2/3 closed is about 200, so I would think a leaking globe valve would be closer to 400. Does anyone know where I could find a more exact approximation for a mostly-closed, 6 inch globe valve? Thanks for your help.
