Hi guys

I was doing a simple exercise to find the sweet spot of a centrifugal pump and when I want to find the value of the intersection of two curves ... I have no idea how to do it.

also ... with that result of the intersection of the first curves I want to intersect another curve.

I tried "Linterp" and "Cinterp" but I was not successful.

thanks guys, you are so cool

Looks like a syntax problem only.
Q, H and WF are already in vector format, no need to place an additional vector "placeholder" inside cinterp.

Thanks friend

I was very sad to see my error xD, it is like "it does not come out because you made a mistake in a + sign" lol

Here I leave the file with a little more detail, in case anyone is interested.
