Challenge Problems
Push your limits with challenges.
Question 1
Given that the viscosity of a certain liquid decreases by 50% when the temperature increases by 30°C, what is the expected viscosity change if the temperature increases by 60°C?
💡 Hint: Consider how viscosity behaves non-linearly at different temperature ranges.
Question 2
How would you evaluate the effects of temperature and pressure on the performance of a hydraulic system that uses a specific oil with documented viscosity changes?
💡 Hint: Cross-reference viscosity data with expected system temperatures.
