  • What are the application of specific gravity? - Quora

    Answer (1 of 8): Specific gravity:- It is used to define the weight or density of a liquid as compared to the density of an equal volume of water at a specified temperature. The temperature used for measurement is usually 39.2o F (4o C), because this temperature allows water to assume its maximum...

    For larger microspheres (such as close to 1mm in diameter) the density needs to match at least to 0.001g/cc in order for the particles to stay suspended for some time. Particles below 200micron might be able to tolerate density mismatch of 0.005g/cc. Particles below 50micron can potentially handle a difference in density of 0.01g/cc.
