no mach no is defined as ratio of local speed of aeroplane to speed of sound. As the altitude increases the True speed of aeroplane increases and speed of sound decreases because of reduction of ambient temperature Hence the value of their ratio should increase at an increasing rate with increase in altitude. Keeping the Mach No constant say, 2 means reduction of speed to a large extent so as to maintain constant Mach No. Therefore same Mach no the aeroplane at higher altitude is flying slower
The mach number is the speed, compared to the speed of sound in air. Thus, mach 1 is the speed of sound, mach 2 is twice (2 times) the speed of sound, mach 3 is 3 times the speed of sound, etc.
There is no plural for the noun 'mach'; the different levels of mach are usually shown by a numeral for various speeds, such as mach 1 or mach 2.
At 30,000 feet, Mach 1 is approximately 661.7 miles per hour (1,070 kilometers per hour). This speed can vary slightly based on temperature and atmospheric conditions, as Mach number is defined relative to the speed of sound, which decreases with altitude due to lower temperatures. At this altitude, the temperature is typically around -30°C (-22°F), affecting the speed of sound.
Maximum speed: Mach 0.96Operating speed: Mach 0.89
the Mach number
To mach for you if you cant spell it.
Ernst Mach .
The homophone for "mach" is "mock."
Mach 2.
Speeds faster than Mach 1 are measured in multiples of Mach, such as Mach 2 (twice the speed of sound), Mach 3 (three times), and so on. Each Mach number represents the speed of an object in relation to the speed of sound.
Mach 1.1 is a speed that is 10% faster than the speed of sound, which varies depending on atmospheric conditions such as temperature and pressure. At sea level and at standard atmospheric conditions, the speed of sound is approximately 1,225 kilometers per hour (about 761 miles per hour). Therefore, Mach 1.1 is roughly 1,350 kilometers per hour (about 839 miles per hour) at that altitude. As altitude increases, the speed of sound decreases, so Mach 1.1 would correspond to a lower speed at higher altitudes.
