Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFConcept:
- Specific gravity is also termed as relative density.
- The relative density/specific gravity of a substance is defined as the ratio of the density, mass or weight of the substance to the density, mass or weight of water at 4°C (Standard atmospheric conditions)
- Specific gravity is the ratio of the specific weight of the liquid to the specific weight of a standard fluid.
- In the case of liquids standard fluid is taken as water with specific gravity 1.
\({\rm{\gamma }} = \frac{{{\rm{Density\;of\;Substance}}}}{{{\rm{Density\;of\;same\;volume\;of\;water}}}} = \frac{{\rm{\rho }}}{{{{\rm{\rho }}_{\rm{w}}}}}\)
