Line 177:
===Example 3 - Entry Losses===
 
This time the flow area in the manhole is 3.57m<sup>2</sup> and 1m<sup>2</sup> in the adjacent culvert whilst the flow is 1m<sup>3</sup>/s for Q<sub>p</sub> and 2m<sup>3</sup>s<sup>-1</sup> for Q<sub>om</sub>. Therefore, V<sub>m</sub> equals:[[File:Vm3.PNG]]
<br>
And V<sub>p</sub>:[[File:Vp3.PNG]]
<br>
From this:

This matches the losses for both incoming pipes as shown in figure x.
 
===Example 3 - Exit Losses===
A'<sub>m</sub> is 3.57m<sup>2</sup> respectively. Therefore, K<sup>exit</sup>:[[File:K exit3.PNG]]
 
The calculated losses match the losses calculated by the TUFLOW.
 
===Example 3 - Outgoing Conduit Losses===
In this model we have two incoming pipes, one with an 90 degree angle between the incoming and outgoing conduit and one with zero.
Recall that:
