If you�re not passing water through the valve, adjustments will need to be. However, since gases are compressible, they are affected by temperature. The ratio of the specific heats, also called adiabatic index, is given by γ = cp cv = 1+ 2 f. It can be assumed that the tests are done with water (unless otherwise noted), using a specific gravity of 1.0, 1.2 centistoke viscosity, and a standard temperature of 60 degrees fahrenheit. This is our valve c v calculator. The valve flow coefficient (c v) is a convenient way to represent flow capacity of a valve across a range of fluids and process parameters.the c v calculator will calculate either c v or flow using the supplied additional parameters of fluid, inlet and outlet.
