POF 3 Questions with Complete Correct Answers | Grade A+
How is lift created Ans: Low pressure above the wing creates a suction upwards Stagnation point Ans: for -the flow stopsregion infront of the wing of high stagnation pressure Turbulent and chaotic air behind the wing Laminar flow Ans: - Laminar flow is a flow regime characterized by high momentum diffusion and low momentum convection Turbulent flow Ans: - low static pressure, and high dynamic pressure Lift Ans: As the component of the total aerodynamic force that is perpendicular to the relative airflow DragAns: is the component of the total aerodynamic forces that is parallel to the relative airflow 250kts Indicated airspeed- how does this affect the air in a venturi Ans: Low static pressure in the middle of venturi- venturi accelerating air to 300knots 250kts Indicated airspeed IF you don't have a high indicated altitude then how can you increase air flow Ans: Make venturi smaller (increase angle of attack) to get to 300knot Aerodynamic Centre Ans: -Fixed Reference point o
