Calculation of Gas Density and Viscosity

COURSE NO: M02-101V
PDH CREDIT: 2
Calculation of Gas Density and Viscosity
Note: This PDH course is a recorded video presentation. It is also offered as a live interactive webinar.
Course Highlights

This online engineering PDH video presentation contains a discussion of, and example calculation of, the density and viscosity of a specified gas at a given temperature and pressure. 

 

The density and/or viscosity of a gas are often needed for specific calculations, such as pipe flow or heat exchanger calculations. The use of the ideal gas law and the Redlich-Kwong compressibility factor for gas density calculation, and use of the Sutherland Formula for gas viscosity calculation are addressed in this video presentation.

 

This 2 PDH online video presentation is intended primarily for chemical, mechanical and environmental engineers, as well as any engineer interested in learning more about calculating the density and viscosity of a gas.
Learning Objectives

This continuing education video presentation is intended to provide you with the following specific knowledge and skills:

  • Calculating the density of a gas of known molecular weight at a specified temperature and pressure at which the gas can be treated as an ideal gas
  • Calculating the compressibility factor for a gas at a specified temperature and pressure, using the Redlich-Kwong equation, if the molecular weight, critical temperature and critical pressure are known
  • Calculating the density of a gas at a specified temperature and pressure for which the gas cannot be treated as an ideal gas, if the molecular weight, critical temperature and critical pressure of the gas are known
  • Calculating the viscosity of a gas at a specified temperature if the Sutherland constant for the gas is known and the viscosity of the gas at a suitable reference temperature is known.
  • Calculating the viscosity of air at a specified temperature and pressure
  • Being able to make all of the calculations described in these learning objectives using either U.S. or S.I. units
