| Abstract: | Basing on Lee-Keslcr equation and the assumption that the flow between the inlet and the throat of a Venturi nozzle is isentropic and one-dimensional, the values of critical flow function C for natural gases at various fractions,temperatures and pressures are obtained successfully.It is shown that these values are close to the data of ISO 9300. |
