Hi, I need to calculate the flow rate through a in tank check valve for compressed air, but im not sure how to analize it, im considering to analize like flow through an orifice???, is this accurate???
Not quite accurate. When calculating flow through a check valve, you need to know the check valve's Cv value. There are other items required to calculate the flow depending upon the media. Here is a link for calculating flows through check valves. It comes from the Check-All Valve website,
