Question 1

Which of the following describes the relation between the lift coefficient (Cl) and the angle of attack (alpha) for a symmetric airfoil in the linear range?

Cl is zero at zero angle of attack and increases linearly with a slope of approximately 2*pi per radian. Cl is positive at zero angle of attack and increases quadratically with alpha. Cl is negative at zero angle of attack and decreases linearly with a slope of -2*pi per radian. Cl is zero at zero angle of attack and remains constant regardless of the angle of attack.

Correct Answer:

Cl is zero at zero angle of attack and increases linearly with a slope of approximately 2*pi per radian.

Question 2

According to Bernoulli's equation for inviscid, incompressible flow, what happens to the static pressure of a fluid when its velocity increases along a streamline?

The static pressure remains constant because total pressure changes. The static pressure decreases to balance the increase in dynamic pressure. The static pressure increases proportionally to the square of the velocity. The static pressure drops to zero immediately when any flow is initiated.

Correct Answer:

The static pressure decreases to balance the increase in dynamic pressure.

Question 3

For a steady, incompressible, one-dimensional flow through a diverging duct, how do the velocity and volumetric flow rate change along the duct?

Velocity increases and the volumetric flow rate increases. Velocity decreases and the volumetric flow rate remains constant. Velocity remains constant and the volumetric flow rate decreases. Velocity decreases and the volumetric flow rate decreases.

Correct Answer:

Velocity decreases and the volumetric flow rate remains constant.

Question 4

The pressure coefficient (Cp) at a point on an airfoil in incompressible flow is defined in terms of static pressure (p), free-stream static pressure (p_inf), and free-stream dynamic pressure (q_inf). What is the value of Cp at a stagnation point?

Cp is equal to 0. Cp is equal to 1. Cp is equal to -1. Cp is equal to infinity.

Correct Answer:

Cp is equal to 1.

Question 5

If the ambient temperature at a specific flight altitude is -40 degrees Celsius, what is the speed of sound at this altitude? (Assume air behaves as a perfect gas with gamma = 1.4 and R = 287 J/kg*K)

Approximately 340.3 m/s Approximately 306.0 m/s Approximately 243.2 m/s Approximately 150.0 m/s

Correct Answer:

Approximately 306.0 m/s
