Challenge Problems

Push your limits with challenges.

Question 1

Consider a cylindrical pipe with a radius of 0.1m experiencing laminar flow at 0.2 m/s. Calculate the momentum flux correction factor assuming parabolic velocity distribution.

💡 Hint: Think about integrating velocity moments to correctly account for the non-uniform distribution.

Question 2

A jet of water strikes a flat surface at an angle. Derive an expression for momentum force considering both the incoming and outgoing velocities.

💡 Hint: Consider how both horizontal and vertical components impact net forces in this scenario.
