I was hoping someone might be able to help or explain to me how the game comes up with how much fuel anengine uses per second i tried to change the nuclear engine and now it uses 300 liquid fuel and 300 oxidizer a second!!!!!! with only a 200 thrust! i know thrust has a factor in the usage number and so does the numbers below the fuel and oxidizer i put both numbers at 0.0001 and it still doesnt help! I get insane fuel demands i'm trying to get my nuclear engine to put out 200-300 thrust and only use 0.01 fuel and oxidizer can it be done????? i know a real nuke uses no fuel but i'll sum it up to the amount of uranium fuel inside the engine! Please help or explain how this process works so i dont keep getting these fuel demands thanks! ~matrix- the kerbin with the broken engine
