Avit 323 Exam 1 Questions And Answers
Mass Flow Theory -
correct answer ✅Constant mass through a smaller area = velocity
increase
Why does static pressure decrease as fluid flows through the
venturi? -
correct answer ✅The airflow has no energy added/subtracted, so
the total energy (KE+PE) must be constant. Therefore, if KE
increases due to constriction, PE must decrease to maintain the
constant total energy
Newton's first law -
correct answer ✅Object at rest will remain at rest unless a force
acts upon it
Newton's second law -
correct answer ✅Force = mass x acceleration
Newton's third law -
correct answer ✅For every action, there's an equal and opposite
reaction
, Avit 323 Exam 1 Questions And Answers
Where does lift act out of? -
correct answer ✅Center of Pressure
Why are all forces in equilibrium at a constant TAS climb? -
correct answer ✅Because there is no acceleration
Why is a loop flown at a constant airspeed and G not symmetrical? -
correct answer ✅the 1g from level flight is used to make the turn
when the airplane is inverted. The loop will have a tighter radius at
the top
Lift equation -
correct answer ✅Lift = 1/2 x density x velocity^2 x CL x sfc area
Characteristic of air that causes the boundary layer -
correct answer ✅Air viscosity; higher viscosity = more friction,
lower viscosity = less friction
Temperature's effect on air viscosity -
correct answer ✅Cold = less viscosity = lower friction
Kinematic viscosity -
correct answer ✅Coefficient of absolute viscosity / density
