The backwashing time is determined by either the turbidity value behind the filter, which must not exceed a set threshold, or by the head loss across the filter medium, which must also not exceed a certain value.

When used to measure open channel flows, packaged metering manholes most commonly integrate a flume or weir ( flumes being most common due to their ability to pass solids, low head loss, and wide operating ranges ).

If the actual sum of our head loss is not equal to 0, then we will adjust all the flows in the loop by an amount given by the following formula, where a positive adjustment is in the clockwise direction.

This entropy is then maximized subject to the constraints on the system, including Kirchhoff's laws, pipe friction properties and any specified mean flow rates or head losses, to give a probabilistic statement ( probability density function ) which describes the system.

We add up the head losses according to the Darcy Weisbach equation for each pipe if Q is in the same direction as our loop like Q1, and subtract the head loss if the flow is in the reverse direction, like Q4.

The winds resulted in significant yield loss due to pod shatter in canola and head loss in both barley and wheat; barley head loss in the order of 1.5 to over 2 tonnes per hectare was observed in many areas of Esperance shire.

In other words, we add the head losses around the loop in the direction of the loop; depending on whether the flow is with or against the loop, some pipes will have head losses and some will have head gains ( negative losses ).
