The chart looks like a mess of curves until you realise every line on it is one property held constant. Fix any two properties and the point where their lines cross gives you all the rest.

You don't get to pick a pump's flow rate. The pump curve and the piping it's bolted to intersect at exactly one point, and that intersection is the only operating point you get.

Both methods solve the exact same heat exchanger sizing problem. The difference is which variable you already know, and that decides which one you can actually use.
