1.	Determine the initial estimation of parasite drag coefficient if, equivalent skin friction coefficient is 0.004 and ratio of wetted area to the reference area is 0.8.(a) 0.0032(b) 1.2(c) 4.2(d) 0.04The question was asked in an international level competition.My question is taken from Aerodynamics topic in chapter Aerodynamics of Aircraft Design
Answer» RIGHT option is (a) 0.0032 The BEST explanation: Parasite DRAG coefficient = equivalent skin friction coefficientarea RATIO = 0.0040.8 = 0.0032.
