HEC-RAS : i want to calculate headloss coming from a direction change
HEC-RAS : i want to calculate headloss coming from a direction change
(OP)
Hello,
I need to integrate a head loss created by a 90° direction change in a unsteady flow model.
I don't see any solution ...
I have think to put a head loss coefficient on a cross section but i can't in unsteady flow. (Headloss = k(v2/2g))
Any body can help me ??

But how much i have to increase n-value ???
Do you know any relation to estimate de headloss if I know the angle ??

The channel's width is 2 meters.
May be somebody know how too calculate the headloss ???
My first idea is to use a headloss coefficient of 1,5 like in pipe ... But i don't now if it is correct ....
