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.
