BE-05 Module Solids in sewers - Question 7
Single-choice question
In order to ensure a problem-free operation of the drains and sewers, one needs a certain minimum slope. As a rough guide, you can apply a simple rule of thumb for calculating this important factor. What is the minimum slope requirement according to this formula in a pipe with a nominal diameter of DN 200?
Your answer is correct. The formula for determining a minimum slope based on the pipes diameter is Icrit = 1000 / DN, thus giving us a correct value for this example of 5 ‰ . However, this result can only be used as a reference value, and does not replace the accurate determination of the required slope.
