2-9. A liquid has a specific gravity of 0.865. What is the density of the liquid at 20 C in the following units: (a) kg/m 3 (b) lb m /ft 3 (c) g/cm 3 (d) kg/lt 2-9. Specific gravity is the ratio of the density of the liquid with respect to the density of water at 20 C which is given by . Given this value, we can compute the answers according to H O 2 3 998.21 kg/m ρ = (a) The density of the liquid is ( ) ( ) H O 2 3 3 0.865 998.21 kg/m 863.45 kg/m liq ρ = γρ = = (b) In Table 2-4 we have the conversion factors that provide 3 3 m m 3 3 kg lb 0.0283 m 863.45 53.87 lb /ft
