The largest single norm flow
Represents the largest single stud agency's standard flow usually between 0.1-0.3l/s.
The average flow
Refers to the average flow through the valve in question, which in normal cases may be seen as a constant.
Refers to likelihood that the average flow is used during peak consumption. Can normally be seen as a constant.
Total norm flow
Sum of tap water standard flows in line to be dimensioned.
The sum of the possible constant tap water flows in the system.
A correction factor based on how much uncertainty in how often the design flow is exceeded. Under normal conditions added uncertainty to 0,001. P>
The flow goes through the line at any one time also commonly referred to as a design flow.
