yay it works

[Ika]

yay i got it, after lots of frustration

 

[Ika]

Please, anyone?

okay, i've never done any of this before but if you work backwards, to get an answer of ~12N, the delta h must be ~30m

i don't see why you would add 25+5 though.... but i'm attempting to google and see how this works

oh god i just realized the plug is 5m from the bottom of the tank, not the top.

EDIT: but then it comes out 14N. GAH! bitten in the ass by procrastination.

EDIT2: wow I'm really tired today. Height is 20m, not 5m, not 25m.
