Ok, I understand that. Regarding Q389) I came across a similar question in the bank:
Q45)
The power output of a normally aspirated piston engine
increases with increasing altitude at constant Manifold
Air Pressure (MAP) and RPM because of the :
A) lower losses during the gas change.
B) lower friction losses.
C) leaner mixture at higher altitudes.
D) lower back pressure. (mark scheme answer)
Lastly, I have one more question:
Q14)
Internal leakage in a hydraulic system will cause :
A) an increased fluid pressure.
B) an increased fluid temperature. (mark scheme answer)
C) fluid loss.
D) a decreased fluid temperature.
Could someone please explain the mark scheme answers.
Thanks.
