Thanks for the advice... as for testing it myself, I don't work in an environment where that's entirely possible being a nuclear plant and all. But thanks again!
I'm trying to find the actual pressure drop across a flow control valve. I was able to find the standard pressure drop using Crane 410 and the "rated Cv" of the valve from the vendor drawing.
My question is in regards to the valves %open. This valve is used as a throttle-type flow...
