Help! Darcy's equation for Resistance Coefficient
Help! Darcy's equation for Resistance Coefficient
(OP)
Hi I need to find the coefficient of resistance K for a reducer with inlet nominal size 32 and outlet nominal size 30. The wall thickness is 1.5 inches. Would I use the equation K = 0.5(1-(dnom/d1)^2)^2 ? If so, which nominal size would i put in for dnom and what value would I plug in for d1? Would I do 0.5(1-(32/27.16)^2)^2 ?
Or if anybody can provide me with some examples of similar problems to look at? I have not been able to find any
Thanks!

The usual reference for this sort of work is the Crane TP 410 manual, but you should find the equations in almost any fluid mechanics book.
