This is a sample of theGas Density calculator. To access the working calculator, pleasesign up for free membership trial. Use this it for quick gas density calculation based on the molecular weight, temperature, pressure and z factor for the gas.
Density of an ideal gases is a function of pressure, molecular weight of the pure gas or mixture and the temperature of the gas.
Ideal gasequation is,
PV = nRT
where,
P = Pressure (bar, atmosphere, Pa)
V = Gaseous volume (m3, cm3)
n = number of gaseous moles (dimensionless)
R =Universal gas constant(J/mol.K, lit.atm/mol.K)
T = Temperature of the gas (K)
Let
M = molecular weight of the gaseous phase
W = n X M = mass of the gaseous phase
To get the gas density formula,
PV = (W/M) RT
点/ RT = W / V
W/V = ρ = mass per unit volume, i.e. density (kg/m3, gm/cm3)
ρ = PM / RT .................. formula for ideal gas density
For a real gas with compressibility factor z,
ρ = PM / zRT ..... formula for real gas density calculation
