Aircraft wings typically operate at high Reynolds numbers because this:

For liquids, viscosity generally decreases as temperature increases, while for gases, viscosity generally increases as temperature increases

This property can be viewed as the fluid’s resistance to shear when different parts of the fluid are in relative motion

Bernoulli’s principle states that an _____________ in the speed of a fluid occurs simultaneously with a decrease in static pressure or the fluid’s potential energy. 

Increasing a wing’s aspect ratio generally results in:

The atmosphere is commonly divided into layers by

Which airspeed is corrected for density effects due to pressure and temperature?

What type of drag is caused by the shape and surface roughness of an object?

What are characteristics of expansion waves (select all that apply)?

The lowest layer of the atmosphere is called the
