Flow Rate

Standard to Actual: Gas Flow

ft3 hr S = ft3 hr A × 520 T+460 × P+14.7 14.7

T=Temperature[°F] P=Pressure[psig]

Standard to Actual: Liquid Flow

 

 

Pressure

P= SG×H 2.31

 

Viscosity

γ= Φ SG

γ=Kinematic Viscosity [cSt] Φ=Dynamic Viscosity [cP] SG=Specific Gravity

 

API

API= 141.5 SG -131.5

Equilibrium

Partial Pressure

The Product of the total pressure P, of the gas, times the mole fraction of that species y(i) in the gas.

Raoult's Law

The partial vapor pressure of each component of an ideal mixture of liquids is equal to the vapor pressure of the pure component multiplied by its mole fraction in the mixture.

 

For a single component in an ideal solution:
