Topic: Re: Compressed pressure losses

posed by 
The role of pipe bends in a piping system is pressure loss due to flowing velocity head. The equation is as follows:
Delta P = K(V2/2g)
Delta P = the pressure drop for the flowing velocity
K = Velocity head loss factor
V = Flowing velocity through the pipe bend
g = Gravitational constant
Typical K values:
0.15 for a long radius elbow
0.25 for a short radius elbow.
