Fluids 1 of 20 What is shear stress? Parallel to ground 2 of 20 What is not an important parameter in describing fluids in terms of aerodynamics? Volume 3 of 20 What is not a characteristic of Reynolds number? It's not dependant on velocity of fluid 4 of 20 What is the are called where you get a velocity gradient? Boundary layer 5 of 20 Velocity at a surface must be what? 0 6 of 20 The velocity does what with increasing distance from surface layer? Increases 7 of 20 In what direction does drag act? Same direction as oncoming air 8 of 20 What is not a type of drag? Surface 9 of 20 What is the drag coefficient not dependant on? Air speed 10 of 20 What is the drag not dependant on? Viscosity of fluid 11 of 20 What is the area behind an object where there is low pressure and high kinetic energy? Wake 12 of 20 In more streamlined objects, the wake is.... Smaller 13 of 20 More wake = More drag 14 of 20 Re < 2300 = Inertial flow 15 of 20 Re > 4000 = Turbulent flow 16 of 20 What is reached when drag = gravity? Terminal velocity 17 of 20 How is the pressure of a fluid related to the flow? Inversely proportional 18 of 20 What is it called when a clockwise rotation is combined with oncoming air to provide lift? Magnus effect 19 of 20 What is lift not dependant on? Surface 20 of 20
