okay so i think I've almost got it but i might be missing out on something:
Vstar/V=Ap/Astar*pstar
substituting in mac number,
Mcstar/Mcr=RHS
substituting C=sqrt(KRT)
gives:
M/Msqrt(KRTstar/KRT)
=sqrt(T*/T)
Tstar/T=Tstar/To*To/T=(1+k-1/2)M*2*2/k+1
and...
Hi everyone!
Homework Statement
Just one part of the lecture notes I couldn't work out how to derrive (apparently we need to know how).
A/A*=1/M[2/(k+1)(1+(k-1)/2*M^2)]^(k+1/2(k-1))Homework Equations
A/A*=1/M[2/(k+1)(1+(k-1)/2*M^2)]^(k+1/2(k-1))
ρ0/ρ=[1+(k-1/2)*M^2]^(1/k-1)...
