How to calculate the speed of a cross flow water turbine?

How to calculate the speed of cross flow water turbine? Help, I'm struggling on our machine design.

You would need a lot more information to do that . Configuration, flow, head, load...more

You need more help than an answer from an internet forum. Talk to your teacher.

Is this what you mean?

Yes, that's what I mean.

What if I have all of the parameters to compute the speed of the cross flow turbine, what formula should I use?

In the steady state, the sum of all torques is zero.

This sounds like homework and it should have been posted in the homework forum. We are not allowed to just spoon feed answers to students. You must show your attempt at a solution first.

This isn't a 1+1=2 question. You need to give a complete description of what you have and need in order for it to be answerable.
