Open Channel, bend head loss

Channel bends should have a center-line radius of 3W to 5W or more, where W is the water surface width of the design flow. For this radius, head loss and the rise in the water surface at the outer bank (superelevation) will be minimal. If the radius must be reduced, the following formula can be used to estimate head loss hL:  

hL= Kb¡¿V^2¡À2g

where Kb=2(W/Rc), W=channel width, Rc=center-line radius, and V=mean velocity

hL=(W/Rc)(V^2/g)
