Challenge Problems
Push your limits with advanced challenges
A model of a dam is scaled down to 1:25. If the actual dam discharges 2500 cubic meters per second, how much should the model discharge to maintain similarity?
💡 Hint: Consider how volume scales with length.
Given a prototype with a wave height of 5 meters and a corresponding model at a scale of 1:10, find the expected wave height for the model.
💡 Hint: Use the scale factor to adjust the dimensions correctly.
