[APD] Flow Coefficient vs. flow rate.

["Douglas Guynn" <d_guynn at sbcglobal.net>]

I have a question for all of you engineering types out there.

Does anyone know the formula that will answer the following question:

If a valve with a max flow coefficient (Cv) will flow 0.040 std. L/min of
air with a 10 psig pressure drop, how would I calculate how much air the
valve would flow with a Cv of 0.005, all other variables the same?

Can you use the formula to account for changes in inlet pressure?
