Coeff of Discharge for Leak
Coeff of Discharge for Leak
(OP)
I'm doing some estimates of choked flow of methane thru a leak in a pipe. Any recommendations for what coefficient of discharge to use? I have used 0.6, but I've seen some examples on the web of 0.72.
My current problem is a 1" hole in a 1-1/4" elbow (1.38" ID),
but I'm also concerned with smaller leaks (.060").
Pressure is low - 30-60 psig.
Thanks

For the small holes, the effect of the pressure loss through the 1 1/2" piping will become less until it's not significant.
