← ScienceWhich effect decreases efficiency of pipeline transport operations?
A)Increased pressure drop requires pumping✓
B)Increased temperature leads to expansion
C)Decreased flow reduces throughput volume
D)Decreased diameter obstructs substance movement
💡 Explanation
Increased pressure drop increases pumping energy, due to viscous dissipation within the pipeline. Laminar shear stress creates this pressure drop; therefore turbulent flow is more impactful rather than other temperature or obstruction issues.
