Challenge Problems

Push your limits with challenges.

Question 1

A researcher is modeling a civil engineering dam project. The actual dam's height is 30m, and the width is 20m. If a model is created at a scale of 1:10, what will be the dimensions of the model? Explain the significance of maintaining geometric similarity in this context.

💡 Hint: Calculate the dimensions by dividing the prototype's dimensions by 10.

Question 2

Explain how dynamic and kinematic similarities can be utilized to predict the water flow patterns in a scaled physical model of a river. What equations would be used to relate their respective numbers?

💡 Hint: Research the equations for Reynolds and Froude numbers.
