NIFE Aerodynamics 2-2-1 Latest Update 100% Pass Total drag eqn (Not EO) Dt = Dp + Di Define Parasite drag and its components Drag that does not aid flight. Has two basic elements: form drag and friction drag. Dp = qf Form drag Results from the disruption of the streamline flow; and the resistance of skin friction.
