Calculate the needed diameter and slope for a sewer pipe. Then you can change again slope and diameter and recalculate.

The Manning Equation is used for Calculation of Pipe Diameter and Slope.

Input data are design flow, desired tractive force, elevations of ground initial and final.

The app can be used in the SI or US units.

Example: The design flow rate for a section of storm sewer between two manholes is: Qdes = 10 l/s. Find a combination of a standard pipe diameter and pipe slope to use for this section of sewer to meet the criteria of minimun tractive force.

The required minimum tractive force for sanitary sewer is 2 N/m2.

See solution of example in the screenshot.
- Initial ground elevation = 10 m (ground elevation of initial and final manholes is used to calculate the ground slope and check that slope of the pipe is not less than ground).
- Final ground elevation = 9 m
- Length of pipe = 60 m
- Desired flow = 40 liters per seconds
- Desired tractive force = 2 N/m2

And as a result of the design, after pressing the calculate button, we get the following results:

Slope (Slope), Pipe diameter, height of water in the pipe (depth / diameter), Velocity and froude number

The slope and diameter can be modified in the result and calculate again.
