Answer to Question #338114 in Calculus for fjfjew

Question

The specific gravity of a liquid is 0.79 kg/m^3. Calculate

the mass density and the specific weight of the liquid.

Answer 1

Specific gravity is the density ratio of the material to that of a reference. Fir liquids the specific gravity is the ratio of the density if the unknown liquid to that of the 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 dencity if water, which is 1000 kg/m³

So the density of the unknown fluid is 790kg/m³. The specific weight is the density times the acceleration due to gravity. Here it's 790 times 9.81 which is 7749.9N/m³
