## Flash Steam

Flash steam ( $$FS$$ ) 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.

### Flash Steam formula

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

Where:

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

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

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

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