Problem

How is the flow in a pipe when using taps and laterals with a customer meter element?

Solution

This will depend on the placement of the lateral and/or tap. If you have a customer meter connected to the junction at the end of the pipe by a lateral, the flow in the pipe will simply be the demanded flow at the node (as well as any other downstream flow). However, if there are taps along the length of the pipe, the flow reported in the pipe will be different. 

Consider a case like the screenshot below.

Here we have a pipe with one customer meter connected to it with a tap. The flow reported in the pipe will half of the total demand on the customer meter. 

Now consider the case below.

Here the flow in the pipe will be the sum of the total demand flow at the downstream-most plus half the flow for the customer meter with the tap on it. 

Basically the flow in the pipe will be reported as the half of the sum of all demands connected with a tap, plus the total flow at the downstream end of the pipe. .
