You have been asked to design an experiment to measure aerodynamic forces on a building using a 1/80 scale replica of the prototype. It has been determined that the wind velocity on the prototype is 32 ft/s when the density of the air is 0.0024 slugs/ft3. You are using a wind tunnel with a maximum velocity of 320 ft/s. Because the temperatures are basically the same, the viscosity of the air for both the model and the tunnel can be considered the same. What air density would you need for the wind tunnel test for dynamic stability? While you are testing, you measure a 48 lbf force on the model. What will the force be on the prototype?
