By critical Mach number you refer to the initial breaking of the sound barrier by an airfoil. As any object moves in air it puts out a bow shock wave. Your motion speeding up the local air. As you...
they work because in every atom there is a neutron, electron and proton. the electron will tell you what the atomic number is and the neutrons and protons will tell you what element it is.
The mach number is the speed of an aircraft, expressed as a fraction of the speed of sound in the atmospheric conditions in which the aircraft is flying. An aircraft flying at mach 1 is flying at the...
Mach no. is dependant on ambient air temp which is associated with a given altitude. As one ascends the temp drops so does the mach no.
Eg. In a standard atmosphere (ISA - international std...
