Flash point of water under pressure
WebMar 1, 2024 · water 1. Introduction Flash evaporation or flashing is essentially a rapid depressurization process that causes the entire liquid to be in an overheated metastable state, eventually returning to a stable state through vaporization of the liquid and heat exchange with the surroundings. 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…

The flash point is a descriptive characteristic that is used to distinguish between flammable fuels, such as petrol (also known as gasoline), and combustible fuels, such as diesel. It is also used to characterize the fire hazards of fuels.
