Physical properties of fluid and fluid transport in piping system

Density, specific volume, specific gravity

Density and partial pressure of component in gas mixture

Flow in pipes and valves theory - full content

If the mixture is consisting of gases than density of each component in the mixture can be calculated as:

Partial pressure of one component in the mixture of gases is:

or:

where is:

• &rho_i - density of component i
• p_i - partial pressure of component i
• p_MIX - pressure of mixture
• r_i - volume ratio of component i
• g_i - mass ratio of component i
• R_i - gas constant of component i
• R_MIX - gas constant mixture
• T - absolute temperature of gas
• Z - compressibility factor

Gas constant for the mixture of gases can be calculated as:

or:

where is:

• r_i - volume ratio of component i
• g_i - mass ratio of component i
• R_i - gas constant of component i
• R_MIX - gas constant mixture
• M_i - molar mass of component i
