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

    I meant overall,

    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?
    So annoyed at myself!!
