Measurement of Gas Discharge Coefficient

Original language description

In case of gas pipeline leakage the gas leakage volume must be determined to calculate costs and losses of the accident. In order to calculate the exact volume of leaked gas it is necessary to specify the crosssection and discharge coefficient of the leak. The laboratory apparatus for the discharge coefficient determination has been built. The vessel pressurized by the gas is freely emptied through the studied orifice into the space at atmospheric pressure. Time course of the pressure and temperature ofgas in the vessel is measured and evaluated in the form of the discharge coefficient. Data on several types of orifice (circular, triangular, square shaped, long narrow slot, flapped semi-open cut in the metal sheet) were measured in critical and sub-critical flow regime.
