🔍 Key Concepts

• Viscosity index (VI) and what a higher or lower VI number means for how an oil’s thickness changes with temperature • How pipe friction losses relate to the viscosity (thickness) of a fluid at a given temperature • Behavior of lubricating oil at elevated temperatures like 130°F

💭 Think About

• At a fixed temperature (130°F), would a lubricating oil with a higher viscosity index be relatively thicker or thinner than one with a lower viscosity index? • How does increasing viscosity affect friction losses in a pipe during flow? Think about whether a thicker or thinner oil causes more resistance. • If two oils are both at 130°F, which viscosity index number would you expect to give the highest actual viscosity (and therefore the greatest friction) at that temperature?

✅ Before You Answer

• Be clear on the definition: higher VI = viscosity changes less with temperature, lower VI = viscosity changes more. • Focus on conditions at 130°F only, not at room temperature or over a wide temperature range. • Connect higher viscosity at 130°F directly to greater pipe friction and match that to the viscosity index choice.
