What is the
relationship between altitude and your variable, ________________?
Answers
will vary.
B.
How does this relationship relate to air density and to the functioning
of a gas turbine engine? Answers
will vary. Students should become aware that a gas turbine engine
needs gas molecules to manipulate to high velocities to create thrust
out the back of the engine. The engine uses Newton's third law of
motion, action-reaction. As gas molecules become scarce the engine's
ability to create thrust becomes more difficult.
C.
Reflection: Which atmospheric factors affect air density?
Altitude, temperature, and air
pressure.
D.
Start EngineSim to test your prediction. [Record the results
of your test in the table provided below.] Answers
will vary.
