Challenge Problems
Push your limits with challenges.
Question 1
A model of a bridge is constructed at a scale of 1:50. If the actual bridge experiences a Reynolds number of 1.2 x 10^6, what must the Reynolds number be for the model if the flow conditions remain similar?
π‘ Hint: Consider how scaling ratios affect fluid dynamics.
Question 2
You are tasked with testing an aircraft model in a wind tunnel. If the full-scale aircraft has a maximum speed of 300 km/h, and the model is scaled down to 1/10th its size, what speed must the model achieve in the wind tunnel to reflect true conditions based on kinematic similarity?
π‘ Hint: Think about speed ratios and mass effects.
