Several kinds of pipe flow calculations can be made with the Darcy-Weisbach equation and the Moody friction factor.  Many of the calculations require an iterative solution, so they are especially suitable for an Excel spreadsheet solution. 

This course includes a discussion of the Darcy-Weisbach equation, the parameters in the equation along with the U.S. and S.I. units to be used, and the types of pipe flow calculations that are suitable for this equation.  A spreadsheet can be used to conveniently make many of the Darcy-Weisbach/friction factor calculations.  Example calculations and discussions of the use of a spreadsheet for making the calculations are also included in the course.

Upon completion of this course, the learner will:

• Be able to calculate the Reynolds number for pipe flow with specified flow conditions
• Be able to determine whether a specified pipe flow is laminar or turbulent flow for specified flow conditions
• Be able to calculate the entrance length for pipe flow with specified flow conditions
• Be able to determine a value of the Moody friction factor from the Moody diagram for given Re and e/D
• Be able to determine a value of the Moody friction factor for given Re and e/D  using the Moody friction factor equations
• Be able to use the Darcy Weisbach equation and the Moody friction factor equations to 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 with specified allowable head loss
