# Wet Steam Entropy

## formulas that use Wet Steam Entropy

\(\large{ s_t = s_s \; \zeta \; + \; \left( 1 \; - \; \zeta \right) s_w }\) |

### Where:

\(\large{ s_t }\) = wet steam entropy

\(\large{ s_s }\) = dry steam entropy

\(\large{ s_w }\) = entropy of saturated water of concensate

\(\large{ \zeta }\) (Greek symbol zeta) = wet steam dryness fraction
