Tīmeklis1 Answer. Whenever there is any disturbance in a compressible fluid, the disturbance is propagated in all the directions with a velocity of sound. The nature of propagation depends on the Mach number. Mach angle:- It is defined as half of the angle of Mach cone. It is denoted by 'a'. Zone of action:- When the Mach number is greater than 1 …
