The speed of sound is equal to 678 mph at temperature -48 degrees F and altitude 30000 feet . 1 mile per hour (mph) = 0.44704 meter per second (m/s) = 1.609344 kilometer per hour (kph) = 1.46666667 foot per second (fps, ft/s) = 0.868976242 knots (kn, kt or kts)....
A free online speed of sound calculator. Speed of Sound vs. Elevation, Temperature and Air Pressure Altitude and speed of sound, temperature and pressure. Water Hammer Rapidly closing or opening valves - or starting stopping pumps - may cause pressure transients in pipelines known as surge or ...
He achieved a speed of about Mach 1.06 at an altitude of 13,000 meters. The first human to travel faster than sound was Soviet cosmonaut Yuri Gagarin, who orbited the Earth at a speed of about Mach 25 in April 1961. The fastest manned aircraft ever flown was the North American X-15,...
He also established the first supersonic wind tunnel at Caltech in 1939.The first human-made object to break the sound barrier was a rocket-powered plane called Bell X-1 piloted by Chuck Yeager in October 1947. He achieved a speed of about Mach 1.06 at an altitude of 13,000 meters. ...
The altitude adjustment of the RA axis allows the mount to be used at latitudes of from zero (the Equator) to about 70 degrees. That is from the top of Finland to the coast of the Antarctica. There is a scale on the side for approximate adjustment in the field, and the mount incorpor...
The speed represented by Mach 1 is not a constant; for example, it is dependent on temperature and atmospheric composition. In the stratosphere it remains constant irrespective of altitude even though the air pressure varies with altitude.
