Water Density by Temperature

Water Density by Temperature Formula

\(\large{ \rho_w =  \frac{ \rho_{H2O}  }{ 1 \;+\; a_v \; \left( T \;-\; T_0  \right)  }   }\)

Where:

\(\large{ \rho_w }\)   (Greek symbol rho) = water density by temperature

\(\large{ \rho_{H2O} }\)   (Greek symbol rho) = normal density of water

\(\large{ T }\) = temperature of water

\(\large{ T_0 }\) = normal temperature of water

\(\large{ a_v }\)  (Greek symbol beta) = volumetric thermal expansion coefficient  (0.0002)
