V=4828.03*5/18//data for velocity is given in Kmph,to convert it to m/s multiply it by 5/18
P=0.0723*10^5;// ambient pressure,N/m^2
T=216.66;//ambient temperature in Kelvin
R=287 ;//gas constant,J/Kg.K
y=1.4; //specific heat ratio for air
M=V/(y*R*T)^0.5 //Mach number
//as M>1 so the flow is supersonic
