Density of biodiesel is an important physical property of liquid fuel and biodiesel. A slight
change in density can affect engine output power. In this work, density of a saturated,
unsaturated fatty acid methyl ester or a biodiesel can be estimated from either (1) its number
of carbon atoms (of fatty acid, z) and number of double bonds (nd): ln ρ=− 0.435–0.0025 z+
85.98/T+ 0.792 z/T+ 4.0 nd/T or (2) its saponification number (SN) and iodine value (IV): ln
ρ=− 0.427–10/SN+ 83.38/T+ 3168.95/(T× SN)+ 11 IV/(T× SN), where T is absolute …
