The Darcy equation gives the head loss in turbulent flow for a circular pipe. The friction factor f depends on the velocity of flow, the pipe diameter, the fluid density and viscosity and the roughness of the pipe.

Correct answer is option C.

Why none of this as we know viscosity acts as a frictional force towards the direction of flow?

According to Darcy's equation friction losses will be more which belongs to turbulence flow. But viscous losses will be more in case of laminar flow. My answer is B.

Yes, it's viscocity.

In fluid flow, friction loss (or skin friction) is the loss of pressure or "head" that occurs in pipe or duct flow due to the effect of the fluid's viscosity near the surface of the pipe or duct.

Turbulence causes Eddy losses not friction losses.

What about turbulence?
