Pentane - Density and Specific Weight vs. Temperature and Pressure
Density , ρ, has units typically [kg/m3] or [lb/ft3], and is defined by the ratio of the mass to the volume of a substance:
ρ = m/V [1]
where m = mass, units typically [kg] or [lb]
V = volume, units typically [m 3 ] or [ft 3 ]
Specific weight , γ, has units typically [N/m 3 ] or [lb f /ft 3 ] is defined by the ratio of the weight to the volume of a substance:
γ = (m * g)/V = ρ * g [2]
where g = acceleration due to gravity, units typically [m/s 2 ] and value on Earth usually given as 9.80665 [m/s 2 ] or 32.17405 [ft/s 2 ]
Tabulated values of pentane density and specific weight at given temperature and pressure (SI and Imperial units) as well as density units conversion are given below the figures.
