WebMay 26, 2005 · The equation Q=Cv sqrt(dp/G) is, in fact derived from the bernoulli eqn. My old freshman physics book shows the derivation of dp=1/2 rho (v2^2-v1^2) and goes on to modify it for negligible v1. Regarding it's accuracy, remember this is for incompressible, inviscid flow. The term Cv is an empirical factor for the huge energy loss you referred to. Webmost of this class the CV will be fixed. When analyzing a control volume problem there are three laws that are always true: 1. Conservation of Mass 2. Conservation of Momentum 3. Conservation of Energy 1.
