Ammonia Gas - Density 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 [m3] or [ft3]
Specific weight , γ, has units typically [N/m3] or [lbf/ft3] 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/s2] and value on Earth usually given as 9.80665 [m/s2] or 32.17405 [ft/s2]
