How is waste pipe size calculated?
What will be an ideal response?
The diameter of pipes used in a sanitary piping system depends on the amount of waste they are to carry. Plumbing codes typically establish the number of drainage fixture units running through each pipe size. A fixture unit is a measure of the probable discharge into the drainage system by the various plumbing fixtures. It is expressed in units of cubic volume per minute. The value for a particular fixture depends on the volume rate of discharge, the time duration of a single discharge, and the average time between successive discharges. A fixture unit is generally equal to 7 1/2 gallons of flow.
