Challenge Problems
Push your limits with advanced challenges
Calculate the wall shear stress for a fluid with a viscosity of 0.89 cP flowing through a pipe at a velocity gradient of 0.15 s^-1.
💡 Hint: Convert viscosity from cP to Pa·s for the calculation.
Describe how the velocity profile would change if the pipe diameter is increased while keeping the flow rate constant.
💡 Hint: Consider the continuity equation in fluid dynamics.
