Question

if the specific gravity of a liquid is 0.79, determine its mass density and specific weight​

Answer 1

Answer:

Assuming that your unknown substance is a liquid.

Specific gravity is the density ratio of the material to that of a reference. For liquids the specific gravity is the ratio of the density of the unknown liquid to that of water. So this way we can find the density of the particular substance which is assumed here to be a liquid by multiplying 0. 79 with density of water which is 1000kg/m^3.

So the density of the unknown fluid is 790kg/m^3.

The specific weight is the density times the acceleration due to gravity. Here it's 790 times 9.81 which is 7749.9N/m^3.
