← ScienceWhich outcome occurs when pumping viscous oil through a narrow pipeline at high flow rates?
A)Increased flow regime becomes turbulent✓
B)Reduced pressure because of laminar flow
C)Lower viscosity due heating effect
D)Decreased friction due smoothed pipe
💡 Explanation
Turbulent flow increases because Reynolds number increases beyond a critical threshold due to the higher oil viscosity and flow rate thus triggering transition. The increased viscous forces cause chaotic fluid motion in the pipe, therefore increasing flow regime rather than maintaining laminar regime under different conditions.
