Flash equation
Webwhat equation should be used to find the flash boundary, as well as the bus gap distances required by the equations. Systems operating at <1 kV use a different equation than those operating between 1 kV and 15 kV. In addition, IEEE 1584 recognizes six equipment classes, as shown in the table at the right. The bus distances used to help The flash evaporation of a single-component liquid is an isenthalpic process and is often referred to as an adiabatic flash. The following equation, derived from a simple heat balance around the throttling valve or device, is used to predict how much of a single-component liquid is vaporized. where: = weight ratio of vaporized liquid / total mass = upstream liquid enthalpy at upstream temperature and pressure, J/kg = flashed vapor enthalpy at downstream pressure and correspo…
