fundamental quantities of aero- ics) dynamics?
-pressure
-temperature
-velocity
-density
-none (all are fundamental quantities of aerodynamics)
Answer:
Question:
2. (T/F) Density and pressure are point true properties
Answer:
Question:
3. Which assumptions are used in the formation of the Standard Atmosphere Model?
Answer:
-air is an ideal gas
-velocity everywhere in the atmosphere is zero
-acceleration of gravity is constant
Question:
4. How many independent properties are required to fully define a point in a flow field?
Answer:
4, maybe 6
Question:
5. The sources of aerodynamic forces on an aircraft are dependent upon how complex the aircraft's
geometry is.
Answer:
false (the forces themselves do vary with geometry)
,Question:
6. If you have steady flow (properties at each point in the flow do not change with time), does this
mean that there are also no accelerations or changes in velocity throughout the flow?
Answer:
no, there can be changes in velocity throughout the flow
Question:
7. What assumptions are required in deriving the Continuity Equation?
Answer:
-steady flow
-uniform, 1D flow
Question:
8. At what speeds is it valid to assume -less than Mach 0.3 that the air is incompressible?
Answer:
Question:
9. What is inviscid flow?
Answer:
-flow where the internal friction acting on fluid elements moving in a flow field is very small and
negligible
-fictitious flow that doesn't exist in reality but is very
useful in simplifying the analysis of many aerodynamic problems
Question:
10. What does Bernoulli's equation im- -the quantity is constant ply about the quantity 5+C(1 /2) 5 5c-
^2 at any point along a streamline in steady, incompressible, inviscid flow?
Answer:
Question:
11. For a system defined as a fixed mass of gas contained within a flex- work done on/by system ible
boundary, what are the only ways in which internal energy of the system can be increased or
decreased?
Answer:
heat transfer in/out of system
, Question:
12. For a flow to be isentropic, it must be both .
Answer:
-adiabatic and reversible
Question:
13. (T/F) If a flow is steady, compressible, and isentropic, its temperature does not change from point
to point in the flow.
Answer:
false
Question:
14. What two variables does the energy -temperature and velocity equation relate for two points along
a streamline in steady, isentropic, compressible flow?
Answer:
Question:
15. (T/F) The speed of sound through air is a function only of the temperature of the air.
Answer:
true
Question:
16. (T/F) When analyzing an open-circuit wind tunnel in a sufficiently large room, the measured
atmospheric pressure in the room can be assumed to be your total pressure.
Answer:
true
Question:
17. (T/F) When analyzing airspeed using a pitot static tube on a flying aircraft, the standard atmospere
pressure at a given altitude can be assumed to be your total pressure
Answer:
false
Question:
18. Equivalent airspeed is different from true airspeed because it is determined using sea level values
of .
Answer:
density
