Q:
What is known as Mach number?
A:
Mach number is the ratio of the speed of an object moving through a fluid divided by the speed of sound. To calculate it, you need to know the speed of the object moving through the fluid, and the speed of sound in the fluid. Mach 1 would mean that the object is moving at the speed of sound, and Mach 2 would be twice the speed of sound.
