Challenge Problems
Push your limits with advanced challenges
Two parallel plates are 0.05 m apart, and the maximum velocity of oil flowing between them is 0.5 m/s. If the viscosity is 0.9 Pa.s, derive the pressure gradient in the flow.
💡 Hint: Start with the relationship between average and maximum velocity.
For a given fluid with shear stress at the wall of 100 Pa and a gap of 0.1 m, calculate the maximum velocity if viscosity is known to be 1.5 Pa.s.
💡 Hint: Recall that tau = mu * du/dy and consider that you can express du/dy in terms of max velocity.
