I have a question which dealing with head loss in laminar flow. 

Is there another head loss formula except the Δh = f (l / dh) (v2 / g 2).

which the formula association of viscosity, length, wall shear stress, and diameter.

Any1 here can list out the head loss formula for me??

Thanks for the concern!
