Partially Full Pipe Flow Calculations

The Partially Full Pipe Flow Calculations online PDH course is a part of the Civil Engineering category of courses.

The Manning equation is used for a variety of types of uniform open channel flow, including gravity flow in pipes, the topic of this course.  This course includes a review of the Manning equation, along with presentation of equations for calculating the cross-sectional area, wetted perimeter, and hydraulic radius for flow of a specified depth in a pipe of known diameter. Numerous worked examples illustrate the use of these equations together with the Manning equation to calculate flow rate and velocity, normal depth, minimum required pipe diameter, required pipe slope or full flow Manning roughness coefficient for partially full pipe flow.

This course is intended for hydrologists, civil engineers, hydraulic engineers, highway engineers, environmental engineers and mechanical engineers.  After completing this course you will have knowledge about the equations for calculating area, wetted perimeter, and hydraulic radius for partially full pipe flow and equations for calculating the Manning roughness coefficient at a given depth to diameter ratio, with a known value of the Manning roughness coefficient for full pipe flow.  Practice in the use of the Manning equation for a variety of partially full pipe flow calculations will be gained through several worked examples.
