Nozzle Energy Balance: Solving Question B

[Ry122]

Im having difficulty with question b in this problem:
[PLAIN]http://img705.imageshack.us/img705/9484/therm.jpg

Heres my attempt:
m(v1^2)*1/2)+h1)=m(v2^2)*1/2)+h2) + Qout
(v1^2)*1/2)+h1)=(v2^2)*1/2)+h2) + Qout
where v1 = 200ms^1
and v2 = 40ms^-1
and h1 = 3104.9kj/kg
And my answer is 22,000kj/kg for h2.
Can anyone see where I'm going wrong?

The blue writing on the question paper are the correct answers.

 

[Ry122]

does anyone know how h = 3128kj/kg
the kinetic energy at the inlet is 20,000kj/kg
while at the outlet it's only 800.
How then could it be that h at the outlet is so low?
Isn't h at the exit dependent on the difference of these kinetic energies?
