ABSTRACT
L=L'- Vh =L1 +..!.[Lz _ Vh ) (3.28)2Aj 2 Aj where Vh =volume of hydrometer (152 H) =67 cm3; Aj = cross-sectional area of the sedimentation cylinder =27.8 cm2 for 1000 mL graduated cylinder.
For an ASTM 152 H hydrometer, the value of L for any reading R (corrected for meniscus) may be obtained from
L =16.3-0.1641R (3.29) Table 3.5 gives the values of L for various hydrometer readings of R for the 152 H
hydrometer.
