1.	Flat plate skin friction coefficient depends upon _____________(a) mach number only(b) reynolds number only(c) mach number, reynolds number etc(d) weight of the aircraftThis question was posed to me during an online interview.I'd like to ask this question from Aerodynamics in chapter Aerodynamics of Aircraft Design
Answer» Correct answer is (a) mach number only To explain I would SAY: Flat plate SKIN friction coefficient depends UPON number of factors including Mach number, Reynolds number, type of flow ETC. Mach number is used to provide information about speed of the object with respect to the speed of SOUND.
