Transonic (or transsonic) flow is air flowing around an object at a speed that generates regions of both subsonic and supersonic airflow around that object. [1] The exact range of speeds depends on the object's critical Mach number, but transonic flow is seen at flight speeds close to the speed of sound (343 m/s at sea level), typically between Mach 0.8 and 1.2.

Hull speed can be calculated by the following formula: where is the length of the waterline in feet, and is the hull speed of the vessel in knots. If the length of waterline is given in metres and desired hull speed in knots, the coefficient is 2.43 kn·m −½.
Metre per hour (American spelling: meter per hour) is a metric unit of both speed and velocity (Vector (geometry)). Its symbol is m/h or m·h −1 (not to be confused with the imperial unit symbol mph). By definition, an object travelling at a speed of 1 m/h for an hour would move 1 metre.
In the alpha-level concept, passenger-only pods were to be 7 ft 4 in (2.23 m) in diameter and were projected to reach a top speed of 760 mph (1,220 km/h) to maintain aerodynamic efficiency. [4] Section 4.4) The design proposed passengers experience a maximum inertial acceleration of 0.5 g, about 2 or 3 times that of a commercial airliner on ...
Masters athletics is a class of the sport of athletics for athletes of over 35 years of age. The events include track and field, road running and cross country running.These are the current world records in various five-year-groups, maintained by WMA, the World Association of Masters Athletes, which is designated by the World Athletics (formerly IAAF) to conduct the worldwide sport of Masters ...
In 1967, 11 years later, Anquetil again broke the hour record, with 47.493 km (29.511 mi), but the record was disallowed because he refused to take the newly introduced post-race doping test. [4] He had objected to what he saw as the indignity of having to urinate in a tent in front of a crowded velodrome and said he would take the test later ...
The AS-1 is believed to have entered service in 1955, initially being deployed on the Tu-4 and later on the Tu-16KS 'Badger-B' strategic bomber, on two under-wing pylons. The missile was also exported to Egypt and Indonesia .
