← ScienceWhich outcome results from decreased crude oil temperature?
A)Increased pumping energy requirements✓
B)Reduced pipe wall shear stress
C)Enhanced turbulent flow regime
D)Decreased cavitation risk to pumps
💡 Explanation
Increased viscosity results from decreased temperature; therefore, friction increases, and pressure drop increases due to viscous drag. Greater pumping energy is required to maintain the same flow rate, rather than reduced shear; turbulence and cavitation depend separately on velocity.
