Line 32:
The resulting headloss value is then applied, when sub-critical flow is experienced, to the standard head loss equation, i.e. dh = K*V<sup>2</sup>/2g. Where K is the loss coefficient, V is the conduit velocity and g the gravitational constant. The equations used for the Engelund loss approach are provided below:

A simple TUFLOW/ESTRY model was set up as shown in Figure 1 with the parameters for the manhole and the links upstream/downstream of the manhole shown in Table 1.
