The drag force on a truck moving at a speed of 95 kmh is to be estimated using the measured data of a similar 1:10 scale model tested in a wind tunnel, Standard air is the fluid in both the prototype and the model, The truck frontal area is 10.7 m* and the measured drag force on the model is 3000 N. Determine: a) the air velocity used in the wind tunnel model tests, and b) the prototype drag force in terms of the measured model drag force.
