Challenge Problems
Push your limits with challenges.
Question 1
Determine how the force required to move a plate through a fluid changes as the fluid's temperature is increased from 20°C to 80°C, if the initial viscosity is known.
💡 Hint: Review how temperature influences viscosity and apply it to the calculations.
Question 2
In a laboratory, a non-Newtonian fluid shows an increasing viscosity with increased shear rate. Describe how this behavior could impact industrial applications.
💡 Hint: Think about how a dilatant fluid behaves under stress.
