Question

37.
Which property of the fluid accounts for the
major losses in pipes ?
(A) Density
(B)
Specific gravity
(C)
Compressibility
(D)
Viscosity​

Answer 1

Answer: viscous property

The property of the fluid accounts for the major loses in pipes.

Explanation: The major loss of the fluid through the pipes due to the frictional resistance between adjacent fluid layers of the liquid sliding over each other, the resistance arises due to the presence of the viscous property of the fluid.

Answer 2

Answer: Viscosity

Explanation:

• The effects of viscosity, or the movement of fluid molecules against each other or against the (potentially rough) wall of the pipe, create "substantial loss" in uniform, straight portions of pipe. Whether the flow is laminar (Re 2000) or turbulent (Re > 4000) has a big impact here:
