Hey,
there are 3 numbers/values in your post measuring energy, and they all go with different units.
(First unit is kl per minute, which I simply don't know what is it . . .
Second unit is kJ, which usually is used for kilo-Joules, which is absolutely unrealistic in this case/application;
And the third unit is "a k", which again denotes I don't know what . . . )
I don't know if you got this formulation from a textbook, or from the tutor's assignment, or created it on your own . . .
In any case, it is not the way to post such a . . . nonsense . . . to the forum.
In distinct of you, we, the tutors, read attentively what you post . . .
