| \( \rho_w \) (Greek symbol rho) = water density by temperature |
\(lbm \;/\; ft^3\) |
\(kg \;/\; m^3\) |
| \( \rho_{H2O} \) (Greek symbol rho) = normal density of water |
\(lbm \;/\; ft^3\) |
\(kg \;/\; m^3\) |
| \( T \) = temperature of water |
\( F \) |
\( F \) |
| \( T_0 \) = normal temperature of water |
\( F \) |
\( F \) |
| \( \alpha_v \) (Greek symbol alpha) = volumetric thermal expansion coefficient (0.0002) |
\(in^3 \;/\; in^3\;F\) |
\(mm^3 \;/\; mm^3\;C\) |
