Homework Statement
Total enthalpy is defined such that:
h+(V^2)/2 = constant ... (1)
h0 is the stagnation enthalpy. Stagnation means V=0. Plug this V into the above, get
h=h0.
Hence h+(V^2)/2 = h0 ... (2)
My question is we already defined V=0, so how could there still be a V^2/2 term in (2)? The total enthalpy is defined as the sum of the static enthalpy plus the kinetic energy. But we've already defined V=0! So shouldn't there be no kinetic energy? I'm really confused on this.
