320kW was the output power (I think). You might get the ecf mark and you should. :smile:

It was 22.2% answer. And it was a 3 mark question. :smile:

I meant overall,
and again it depends on the Output Power you calculated.

For question 1, I got the answer to the penultimate part, but then stupidly thought it was wrong so wrote something random down. Then I used that answer/320000 x 100 for the last part.
Anyone know if I would get any marks for any of them? :frown:

So annoyed at myself!!
