← ScienceWhich outcome occurs when incompressible fluid viscosity increases in Bernoulli's equation for pipeline flow?
A)Increased head loss over distance✓
B)Elevated fluid kinetic energy profile
C)Decreased flow turbulence overall
D)Uniform pressure distribution across pipe
💡 Explanation
Increased viscosity raises the frictional forces resisting flow; the friction is described via Darcy-Weisbach equation and apparent in head loss. Thus, Momentum Diffusion becomes significant because energy dissipates resisting the motion; therefore there’s head loss, rather than elevated energy consistent with lower viscosity.
