Mach number (M) is a dimensionless quantity that compares the flow velocity to the speed of sound. At Mach 1, the flow velocity is equal to the speed of sound, which varies with temperature. Learn how to calculate and classify Mach numbers and see examples of high-speed flows. Mach1 is equal to about 741 miles per hour. Mach is the ratio of an object's speed to the speed of sound. For example, something traveling at Mach 5 is traveling at 5 times the speed of sound. The speed of sound varies depending on many factors. In dry air, at 0 degrees Celsius, the speed of sound is about 331.3 meters per second. See full list on calculateme.com Mach number (M) is a dimensionless quantity that compares the flow velocity to the speed of sound. At Mach 1, the flow velocity is equal to the speed of sound, which varies with temperature. Learn how to calculate and classify Mach numbers and see examples of high-speed flows. What does Mach 1 mean?to represent the flow boundary past the local speed of sound. In other words, pushing past the sound barrier is defined as Mach 1. So how fast do you have to be going to do that? When we hear the term Mach 1 it is easy to assume it is the speed of sound through Earth's atmosphere. However this term is more loaded than you might think.What is Mach 1 to mph?Mach 1 to mph conversion. Mach 1 is equal to about 741 miles per hour. Mach is the ratio of an object's speed to the speed of sound. For example, something traveling at Mach 5 is traveling at 5 times the speed of sound. The speed of sound varies depending on many factors.Is Mach 1 a fixed speed?What people don't realize, though, is that while Mach 1 is the speed at which an aircraft reaches the speed of sound, it's not a fixed speed. The key thing here is that the speed of sound changes relative to the temperature and density of the air you are flying through. At sea level this is around 330 meters per second or 767 miles per hour.How do you know if an aircraft is flying at Mach 1?It is said that the aircraft is flying at Mach 1 if its speed is equal to the speed of sound in air (which is 332 m/s or 1195 km/hr or 717 miles/hour.) An aircraft flying at Mach 2 is flying at twice the speed of sound in air, etc. Mach numbers are named after Ernst Mach (1838-1916), an Austrian philosopher and physicist. · At sea level this is around 330 meters per second or 767 miles per hour. But at higher altitudes Mach 1 can be considerably slower than at sea level. "Breaking the sound barrier" sounds dramatic...
