Challenge Problems
Push your limits with challenges.
Question 1
Assume you have a fluid with an initial viscosity of 0.01 Pa.s at 20°C. If it exhibits a decrease in viscosity proportional to a 0.5% change for every 10°C increase, calculate its viscosity at 60°C.
💡 Hint: Consider temperature’s effect as given in the problem.
Question 2
Explain how you would conduct an experiment to measure the dynamic viscosity of a non-Newtonian fluid and what observations you would make.
💡 Hint: Think about the steps required in a standard fluid mechanics experiment.
