The aerodynamic drag of a new sports car is to be predicted at a speed
of 50.0 mi/h at an air temperature of 25 °C. Automotive engineers build
a one-fifth scale model of the car to test in a wind tunnel. It is winter and
the wind tunnel is located in an unheated building; the temperature of
the wind tunnel air is only about 5 °C. Determine how fast the engineers
should run the wind tunnel in order to achieve similarity between the
model and the prototype. Properties of air at 25 °C are density 1.184
kg/m3 and dynamic viscosity is 1.849 * 10-5
, at 5 °C density is 1.269
kg/m3 and dynamic viscosity 1.754 * 10-5.
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
