WebJul 11, 2016 · However, HYSYS has an orifive model in the valve i think. Use the (defualt i think) value for a PSV calculation for the correction factor (around 0.62-0.65 i think) Thank you for your comment, i am still a bit blur with this. Use the valve but change the model. Can't check Hysys but I think you can do that. Thanks. WebAug 17, 2015 · I would guess there will be choked flow where the downstream pipe, that the orifice is in, ties into the main pipe. This plus frictional loses will put backpressure on the downstream side of the orifice. If this backpressure causes the orifice pressure ratio to exceed the critical pressure ratio, there will be subsonic flow through the orifice.
