Spreadsheet Use for Partially Full Pipe Flow Calculations

COURSE NO: C03-052
PDH CREDIT: 3
Spreadsheet Use for Partially Full Pipe Flow Calculations
Course Highlights

This online engineering PDH 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.  A spreadsheet for making partially full pipe flow calculations is included with this course and its use is discussed and illustrated through worked examples.

 

The Manning equation can be used for uniform flow in a pipe that is partially full, but the Manning roughness coefficient needs to be considered to be variable dependent upon the depth of flow.

 

This 3 PDH online 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.

Learning Objectives

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

  • Ability to calculate the cross-sectional area of flow, wetted perimeter, and hydraulic radius for less than half full flow at a given depth in a pipe of given diameter.
  • Ability to calculate the cross-sectional area of flow, wetted perimeter, and hydraulic radius for more than half full flow at a given depth in a pipe of given diameter.
  • Ability to use Figure 6 in the course material to determine the flow rate at a given depth of flow in a pipe of known diameter if the full pipe flow rate is known or can be calculated.
  • Ability to use Figure 6 in the course material to determine the average water velocity at a given depth of flow in a pipe of known diameter if the full pipe average velocity is known or can be calculated.
  • Ability to calculate the Manning roughness coefficient for a given depth of flow in a pipe of known diameter, with a known Manning roughness coefficient for full pipe flow.
  • Ability to use the Manning equation to calculate the flow rate and average velocity for flow at a specified depth in a pipe of specified diameter, with known pipe slope and full pipe Manning roughness coefficient.
  • Ability to calculate the normal depth for a specified flow rate of water through a pipe of known diameter, slope, and full pipe Manning roughness coefficient.
  • Ability to calculate the minimum required pipe diameter for a specified flow rate of water through a pipe of known slope, full pipe Manning roughness coefficient and a target value for y/D.
  • Ability to calculate the required pipe slope for a specified flow rate of water through a pipe of known diameter, depth of flow, and full pipe Manning roughness coefficient.
  • Ability to calculate the value of the full pipe Manning roughness coefficient for a specified flow rate of water through a pipe of known diameter, slope, and depth of flow.
  • Ability to carry out the calculations in the above learning objectives using either U.S. units or S.I. units.
  • Ability to use the spreadsheet included with this course to make partially full pipe flow calculations.
