At a point in the flow over a high-speed missile, the local velocity and temperature are 300 ft/s and 500oR, respectively. Calculate the Mach number M and the characteristic Mach number, M* at this point.

Answer :

Answer:

0.267

Explanation:

The Mach number is given by the following formula:

[tex]Ma = \frac{v}{c}[/tex]

where v = speed of the object

           c= speed of air

Ma         = Mach number

   From the data:

Velocity of the object = 91.44 m/s

Velocity of air =  343 m/s        

 Therefore, the Mach number is given by the following formula:

Ma = [tex]\frac{91.44}{343}[/tex]

      = 0.267
