Unformatted text preview: net F air w g V d = and V d F air F net w g = Now in order to find the specific gravity of the person, we need his/her density: F air M g = g V d = g F air F net ( ) w g = Simplifying this expression we get: F air w F air F net ( ) = Now if we call the density of water at 4 deg C w4C then: F air w4C w w4C F air F net ( ) = SG SG w F air F net ( ) = Solving this expression for the specific gravity of the person SG, we get: SG SG w F air F air F net =...
