Course Description


This course is intended primarily for civil engineers, mechanical engineers, chemical engineers, and environmental engineers. After completing this course you will be able to make calculations with the Darcy Weisbach equation and the Moody friction factor equations to calculate several different unknown pipe flow parameters when sufficient input data is provided. You will also be prepared to use Excel spreadsheets to efficiently make the calculations.



Course Objectives


Upon successful completion of this course, the participant will be able to:

  • Calculate the Reynolds number for pipe flow with specified flow conditions
  • Determine whether a specified pipe flow is laminar or turbulent flow for specified flow conditions
  • Calculate the entrance length for pipe flow with specified flow conditions
  • Determine a value for the Moody friction factor using the Moody diagram for given Re and epsilon/D
  • Calculate a value for the Moody friction factor for specified Re and epsilon/D, using the appropriate equation for f
  • Calculate the frictional head loss and frictional pressure drop for a given flow rate of a specified fluid through a pipe with known diameter, length and roughness using the Darcy Weisbach and Moody friction factor equations
  • Calculate the required diameter for a given flow rate of a specified fluid through a pipe with known length and roughness, with specified allowable head loss using the Darcy Weisbach and Moody friction factor equations
  • Calculate the fluid flow rate through a pipe with known diameter, length and roughness, with specified frictional head loss using the Darcy Weisbach and Moody friction factor equations
