Q127
Ratio of inertia force to elastic force is known as
A.
Mach number
AnswerB.
Froude number
C.
Reynold’s number
D.
Weber’s number
Answer: Option A
Solution
Answer: Option A
Solution:
The Mach number (Ma) represents the ratio of the speed of an object (such as an aircraft) to the speed of sound in the surrounding medium. It is used to characterize compressible flows, particularly in aerodynamics. The Mach number helps determine the behavior of fluid flows at high speeds where the effects of compressibility become significant.
