About the Cv value of the regulating valve

Thread Content

Please tell me the calculation formula for the gas in the Cv value calculation formula of the regulating valve.: When ΔP =(P1/2):Cv=Q/(249 * P1) * SQRT(G * (273+T)) What parameter is 287 here? What is its definition?

It seems to be a constant derived from a unit. When calculating, keep the unit uniform and the derived constant has no specific meaning.
