a=patial (p)/partial (rho)|s=constant 
a=sqrt(grama*R*T) a:sound speed grama=1.4 T:temperature,R=278
p:pressure, rho:density, s:entropy
Mach=V/a V:speed Mach:馬赫數
Mach angle=sin(-1) (1/Mach)
Temperature is different with the altitude,so that sound speed is
not always constant!
看不懂請自己翻"空氣動力學"課本,裡面有詳細解釋sound speed ^_^|||
