WebMay 8, 2024 · The speed of sound (otherwise known as Mach 1) varies with temperature. At sea level on a “standard day,” the temperature is 59°F, and Mach 1 is approximately 761 mph. As the altitude increases, the temperature and speed of sound both decrease until about 36,000 feet, after which the temperature remains steady until about 60,000 feet. WebMay 31, 2013 · On Earth, the speed of sound at sea level — assuming an air temperature of 59 degrees Fahrenheit (15 degrees Celsius) — is 761.2 mph (1,225 km/h). Because gas …

WebSupersonic speed is the speed of an object that exceeds the speed of sound ( Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level, this speed is approximately 343.2 m/s (1,126 ft/s; 768 mph; … WebFeb 2, 2024 · What is the speed of sound at sea level? A plane flying Mach 1.0 at sea level is flying about 1225 km/h (661 Knots, 761 mph), a plane flying Mach 1.0 at 30000 ft is flying 1091 km/h (589 knots, 678 mph) etc. Speeds below Mach 1 are called subsonic, between Mach 0.8-1.2 Transonic and above Mach 1.2 Supersonic. long-wished

WebFeb 28, 2024 · The speed of sound in fps at sea level is 1100 feet per second, and the speed of sound in air fps is 1125 feet per second. Also, the speed of sound varies with the … WebThe speed of sound, also known as Mach 1, changes throughout the atmosphere based on the temperature at any given altitude. Probably the most important value to remember, however, is the speed of sound at sea level. Based on the standard atmospheric model, this value has been defined to be 1,116.4 ft/s 340.3 m/s 761.2 mph 1,225.1 km/h 661.5 knots WebThe speed of sound is 750 miles per hour near sea level then drops to 650 mph as altitude increases then continues up to 1000 mph with increasing altitude. We will assume near sea level. First we convert the units 750 mph = 1100 feet per second. At Mach 10 it is 11000 fps so time to travel 100 Feet is 0.0091 Sec. hop on hop off rouen
