CHEN 3101 Chapter Notes - Chapter 12: Mass Flow Rate, Ideal Gas, Superheated Water
Document Summary
Relative amounts of components in a mixture can be expressed as mass fraction: mi = mass of component i, m = total mass of the mixture. Gravimetric analysis = listing of the mass fractions of components in a mixture. The sum of mass fractions in a mixture = unity. Amounts of components in a mixture can also be expressed as mole fractions: ni = moles of component i. Volumetric analysis = analysis of mixture in terms of mole fractions. Sum of mole fractions in a mixture = unity. The apparent (or average) molecular weight of the mixture, m, is: 12. 2 relating p, v, and t for ideal gas mixtures. Dalton model an idealized model for mixtures where all components behave as ideal gas as if it were alone at the temperature t and volume v and and. Individual components only exert partial pressure, which can be expressed as: The dalton model is a special case of the additive pressure rule:
