Hydrostatic Weighting

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

Hydrostatic weighting, abbreviated as \(\rho_b\), also called underwater weight, is how you can determine the average density of any object without nead for volume or measuring the mass per unit volume.


Hydrostatic weighting formula

\(\large{ \rho_b = \rho_w  \;  \frac { W_b } { W_b \;-\; W_{im} } }\)   


\(\large{ \rho_b }\)  (Greek symbol rho) = density of body

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

\(\large{ W_b }\) = weight of body

\(\large{ W_{im} }\) = weight of immersed body
