Challenge Problems
Push your limits with challenges.
Question 1
A 50-meter-long pipe with a diameter of 0.2 m has a wall shear stress of 0.02 Pa. Calculate the pressure drop per unit length.
💡 Hint: Use the formula derived for pressure drop.
Question 2
Illustrate how the transition from laminar to turbulent flow affects pressure drop if the diameter of the pipe is halved while the viscosity remains constant.
💡 Hint: Relate the concept of area to flow resistance.
