Challenge Problems
Push your limits with challenges.
Question 1
What is the kinetic energy per unit volume of a fluid with density 1,000 kg/m^3 flowing at a velocity of 2 m/s? Discuss how viscosity would factor into energy loss during flow.
💡 Hint: Consider how energy is lost to friction in a flowing fluid.
Question 2
Design an experiment to measure the viscosity of a non-Newtonian fluid like ketchup. What factors would you need to consider?
💡 Hint: Think about how the fluid behaves under different conditions.
