Question 22
AEMCQ1 markNeeds review
On Day 1, an aircraft flies with a speed of V₁ m/s at an altitude where the temperature is T₁ K. On Day 2, the same aircraft flies with a speed √1.2 V₁ m/s at an altitude where the temperature is 1.2 T₁ K. How does the Mach number M₂ on Day 2 compare with the Mach number M₁ on Day 1?
Assume ideal gas behavior for air. Also assume the ratio of specific heats and molecular weight of air to be the same on both the days.
