Im having difficulty with question b in this problem:(adsbygoogle = window.adsbygoogle || []).push({});

[PLAIN]http://img705.imageshack.us/img705/9484/therm.jpg [Broken]

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.
