# Flash Steam

Written by Jerry Ratzlaff on . Posted in Thermodynamics

Flash steam, abbreviated as FS, is when hot condensate is released from a high pressure to a lower pressure steam.  This steam is the same as normal steam, the name is just given to explain how the steam is formed.

## formulas that use Flash Steam

 $$\large{ FS = \frac { h_i \; - \; h_o } { L } }$$

### Where:

$$\large{ FS }$$ = flash steam

$$\large{ L }$$ = latent heat of saturated water at outlet

$$\large{ h_i }$$ = specific enthalpy of saturated water at inlet

$$\large{ h_o }$$ = specific enthalpy of saturated water at outlet
