Challenge Problems

Push your limits with challenges.

Question 1

A cylindrical pipe of varying diameter is subjected to pressure at one end. Develop a dimensionless equation relating pressure, viscosity, diameter, and flow velocity, and discuss its physical significance.

💡 Hint: Consider how each variable interacts in contributing to the flow within the pipe.

Question 2

Given an experimental setup measuring the effect of fluid density, viscosity, and gravitational force on wave period, derive the relationships using the Buckingham Pi theorem.

💡 Hint: Remember to express everything in dimensionless terms, considering how wavelength interacts with the other variables.
