What is Mach Power?
1 Answers
Mach is a unit of speed, commonly used to indicate the flight speed of aircraft, missiles, and rockets. Mach 1 represents one times the speed of sound. The speed conversion of Mach is generally equivalent to 340.3 m/s (meters per second), approximately equal to 1225 km/h (kilometers per hour), 761.2 mph, or 1116 ft/s. Below is extended information about Mach: 1. Temperature: The specific speed per "one Mach" is not fixed. At lower temperatures, the speed of sound is lower, and thus the corresponding speed for one Mach is also lower. Therefore, relatively speaking, it is easier to achieve higher Mach numbers at high altitudes than at low altitudes. 2. Fluid: When the Mach number Ma<0.3, the pressure exerted on the fluid is insufficient to compress the fluid and only causes fluid flow. Under these conditions, the fluid density does not change with pressure. This type of flow field is called subsonic flow (Subsonic-flow), and the flow field can be considered an incompressible flow field.
