Challenge Problems
Push your limits with challenges.
Question 1
A fluid's viscosity at 25°C is 0.89 mPa·s. If its temperature is raised to 45°C, based on the Sutherland correlation, estimate the new viscosity assuming it behaves as a Newtonian fluid. Given constants a = 1.8, b = 0.54.
💡 Hint: Ensure that you are using the absolute temperatures.
Question 2
Describe a real-world scenario where understanding the difference in viscosity between a Newtonian and Non-Newtonian fluid could impact industry practices.
💡 Hint: Think about how texture impacts consumer experience.
