The purpose of this problem is to give you a feel for the magnitude of reynolds number appropriate to real airplanes in actual flight. a. consider a dc-3 s. the wing root chord length (distance from the front to the back of the wing where the wing joins the fuselage) is 14.25 ft. consider the dc-3 flying at 200 miles per hour at sea level. calculate the reynolds number for the flow over the wing root chord. (this is an important number, because as we will see later, it governs the skin-friction drag over that portion of the wing.)b. consider a f-22. the chord length where the wing joins the center body is 21.5 ft. consider the airplane making a high-speed pass at a velocity of 1320 ft/s at sea level (mach 1.2). calculate the reynolds number at the wing root.
