The Mach number is a dimensionless quantity that represents the ratio of an object’s velocity to the speed of sound in the surrounding medium. It is named after the Austrian physicist and philosopher Ernst Mach, who made significant contributions to the study of shock waves. Mathematically, the Mach number (M) is defined as M = V / Vs, where V is the velocity of the object and Vs is the speed of sound.
Introduction to the concept of the speed of sound
The speed of sound is the rate at which sound waves propagate through a medium. It is determined primarily by the medium’s temperature and molecular composition. In dry air at 20 degrees Celsius, the speed of sound is approximately 343 meters per second (1,125 feet per second). However, the speed of sound can vary in different mediums, such as water or solids.
Relationship between Mach and the speed of sound
The Mach number provides a convenient way to express an object’s velocity relative to the speed of sound. When an object is traveling at Mach 1, it is moving at the exact speed of sound. Similarly, when an object exceeds Mach 1, it is said to be supersonic. The relationship between the Mach number and the speed of sound is crucial in understanding the behavior of objects traveling at high speeds.
As an object approaches and exceeds Mach 1, it experiences a phenomenon known as compressibility effects. These effects include shock waves and sonic booms, which are generated as the object surpasses the speed of sound. Understanding the Mach number and its relationship to the speed of sound is fundamental for designing and operating supersonic and hypersonic vehicles.
While the focus of this article is on Mach 2, which is twice the speed of sound, it is important to note that Mach numbers can go well beyond Mach 2.
