All About Viscosity

COURSE NO: H06-002
PDH CREDIT: 6
COURSE PROVIDER: William Hauserman, P.E.
All About Viscosity
Course Highlights

This online engineering PDH course will present and define, by illustrations and discussion, the basic principles of rheology, which is the science of viscosity, of gasses and liquids, and how viscosity varies with respect to other variables, with case examples to illustrate the design problems to be expected.

 

Viscosity is a fundamental property of any fluid, gas or liquid, that determines its resistance to motion against a containing surface (pipes) or adjacent increments of itself.  It is an essential parameter in all formulas for fluid flow and heat transfer calculations, in which it is normally entered as a fixed value for any set of conditions.  For many liquids, however, viscosity is not a constant value but may vary, sometimes over an extreme range, in response to the temperature and flow rate through pipes.  The pattern and direction of this variation is of many forms, including thixotropic/shear-thinning, where the viscosity decreases with flow velocity, or rheotropic, where it increases with flow, and several other phenomena.  This course covers the basic definition and means of measuring viscosity and identification of non-linear fluid behavior, in which viscosity varies with respect to other variables (flow rate, pipe diameter, temperature) with which it is used in calculation of flow resistance. This course includes examples of complex rheological behavior of a wide variety of fluids, and how to recognize and deal with such un-welcome variability and uncertainty in practical engineering calculations for equipment design.

 

This 6 PDH online course is applicable to chemical and mechanical engineers who are interested in design or analysis of processes involving fluid flow and heat transfer, prediction of which involves knowing or estimating the viscosity of flowing fluids.

Learning Objectives

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

 

  • Understanding the nature of viscosity and its different types of variation with respect to other process variables
  • Knowing how to evaluate available rheological data for various kinds of fluids
  • Learning how to perform basic conceptual engineering calculations for fluid flow and heat transfer using complex rheological data
  • Familiarizing with the design problems that may arise due unexpected variation in such data
