mach number
In fluid dynamics, the Mach number (M or Ma) is a dimensionless quantity representing the ratio of flow velocity past a boundary to the local speed of sound. ,In aerodynamics, the critical Mach number (Mcr or M* ) of an aircraft is the lowest Mach number at which the airflow over some point of the aircraft reaches the ... , Mach number equals object speed divided by speed of sound. Pictures of aircraft at subsonic. As an aircraft moves through the air, the air ...,Subsonic and Supersonic speed. If the mach number is < 1, the flow speed is lower than the speed of sound - and the speed is subsonic. If the mach number is ... , ,名詞解釋: 飛行體速度V 與聲音速度C 之無因次比值V/C稱為馬赫數，通常以M＝V/C 表示之，以紀念奧國出生之物理學家馬赫博士(ernst Mach, 1838~1916)，如圖1所 ... , Mach number, in fluid mechanics, ratio of the velocity of a fluid to the velocity of sound in that fluid.
