Uniform Open Channel Flow and The Manning Equation -2 PDH

Email
Flow of a liquid may take place either as open channel flow or pressure flow. Pressure flow takes place in a closed conduit such as a pipe, and pressure is the primary driving force for the flow. For open channel flow, on the other hand the flowing liquid has a free surface at atmospheric pressure and the driving force is gravity. Open channel flow takes place in natural channels like rivers and streams. It also occurs in manmade channels such as those used to transport wastewater and in circular sewers flowing partially full.

Learning Objectives

At the conclusion of this course, the student will

  • Know the differences between laminar & turbulent, steady state & unsteady state, and uniform & non-uniform open channel flow.

  • Be able to calculate the hydraulic radius for flow of a specified depth in an open channel with specified cross-sectional shape and size.

  • Be able to calculate the Reynolds Number for a specified open channel flow and determine whether the flow will be laminar or turbulent flow.

  • Be able to use tables such as the examples given in this course to determine a value for Manning roughness coefficient for flow in a manmade or natural open channel.

  • Be able to use the Manning Equation to calculate volumetric flow rate, average velocity, Manning roughness coefficient, or channel bottom slope, if given adequate information about a reach of open channel flow

  • Be able to use the Manning Equation, with an iterative procedure, to calculate normal depth for specified volumetric flow rate, channel bottom slope, channel shape & size, and Manning roughness coefficient for a reach of open channel flow

  • Be able to carry out a variety of calculations for full or partially full flow under gravity in a circular pipe.

Previous comment from Lance is correct. really an overview without much substance. needs an review by author to insert technical content. Too simple

I haven't read the whole course, but I have looked at the test questions. Just beware that the correct answers are not given for questions 4 and 10. Number 4 correct answer is not shown, whether you interpret the 1:2 as H:V or V:H. The correct answer for Number 10 is one decimal place off from one of the choices shown.

Thank you for your quick response.  I can take unlimited courses for up to one year?  That means I can apply some of the courses for this year’s  deadline, and take additional courses after that toward my next period deadline!

I already finished about 80 Hours and passed all the quizzes. Highly Appreciated!
