In dry air, at 0 degrees Celsius, the speed of sound is about 331.3 meters per second.For our calculation, one Mach is equal to 343 meters per second, which is the speed of sound at 68 degrees Fahrenheit with low humidity. Here are step-by-step instructions showing you how to get Mach 2.25 in mph: 1) Multiply 2.25 by 343 to get Mach 2.25 in meters per second: 2.25 × 343 = 771.75 Mach 2.25 = 771.75 meters per second. 2) There ... How fast is Mach 1, Mach 2, Mach 4, Mach 6, Mach 15, Mach 20, etc. at different altitudes? - question from name withheld. Background information can be found in two additional questions we've already adressed covering the speed of sound and how fast is Mach 1.But since we get various versions of this question over and over again, we …For our calculation, one Mach is equal to 343 meters per second, which is the speed of sound at 68 degrees Fahrenheit with low humidity. Here are step-by-step instructions showing you how to get Mach 2.25 in mph: 1) Multiply 2.25 by 343 to get Mach 2.25 in meters per second: 2.25 × 343 = 771.75 Mach 2.25 = 771.75 meters per second. 2) There ... Therefore, the Mach angle is 90 at , and its value decreases quickly beyond Mach 1, as shown in the figure below. Notice that even by a Mach number of 2, the Mach cone is already swept back 60 to a half apex angle of . For hypersonic speeds, the Mach angle is so steep that it can touch the body’s surface, so a blunt or bluff body shape is ... Mach 1 is equal to 0.343 kilometers per second, so use this simple formula to convert: kilometers per second = Mach number × 0.343. The speed in kilometers per second is equal to the Mach number multiplied by 0.343. For example, here's how to convert Mach 2 to kilometers per second using the formula above. Mach 2 = (2 × 0.343) = 0.686 km/s.M = v (ρ / E) 1/2 (2) where . ρ = density of fluid (kg/m 3, lb/ft 3) E = bulk modulus elasticity (N/m 2 (Pa), lb f /in 2 (psi)) The bulk modulus elasticity has the dimension pressure and is commonly used to characterize the fluid compressibility. The square of the Mach number is the Cauchy Number. M 2 = C (3) Mach number: [noun] a number representing the ratio of the speed of a body (such as an aircraft) to the speed of sound in a surrounding medium (such as air)..
