Correct Answer : wetted area
Explanation : Wetted area is the total exposed area which would get wet if we immersed body in fluid. Volume is product of area and length or depth. Length is measurement of how long an object is. Wing planform is shape of wing when viewed from top.
Correct Answer : Option (A) : 3.42 per m
Explaination : Given, Stop=10m2, Aside=14m2, L = 10m.Now ratio of wetted area Aw and volume V is given by,Aw/V = 2*L*(Stop + Aside) / (Stop*Aside)Aw/V = 2*10*(10+14) / (10*14) = 20*24/140 = 3.42 per m.
Correct Answer : Option (A) : 4m²
Explaination : Given, planform area = 2m².Since, wing is paper thin wetted are = 2*planform area = 2*2 = 4m².
Correct Answer : Option (B) : 16.16m²
Explaination : Given, Aw = 64.64m².Now, average projected area A = Aw/4 = 64.64/4 = 16.16m².
