I want to know some of the measuring techniques and necessary components for measuring the pressure of a rotating flow in a pipe. I came across something called a five-hole probe, and some suggestions saying something like a fast response pressure probe that moves along the axial direction? Can...

Yes, but I would like to have a better insight into the advantages and disadvantages of this particular application. I kind of know what is the essential components for the dynamometers mentioned above, like water supply or electric supply. But I'm not sure if this is all the additional...

I'm designing a test rig for a 1m diameter Tesla Turbine. I'm currently choosing between a hydraulic dynamometer and an eddy current dynamometer. What are the advantages and disadvantages of each? Is there a better dynamometer option for measuring the torque and power? And what are the essential...

Thanks very much!

I'm hoping to find a site that sells this type of size of compressor or air recievers, I don't know where I can find them.

Thank you for the link. Isn't there some industrial size compressor that can do the job? instead of having 10 of them?

IRstuff, thanks for your reply! I'm not actually building it, I'm only designing one. Consider this test rig to be used for industrial testing, so it's not any home experiments and I'm not worried about the budget as well. My turbine is 1m in diameter, so I think a high scfm makes sense...

I'm designing a turbine test rig, and for the air supply system, I'm thinking to have a compressor connected to an air receiver, then to a back pressure regulator, and finally to a converging nozzle connected to the turbine. There are some known variables, the turbine nozzle inlet diameter is...

Thank you very much!

It is just a free-spinning disc in a Tesla Turbine, but for this problem, I can assume no net axial force acting on the disk due to pressure. No, the stresses will not vary if I only based on the equations I found. Because nearly all of the equations I found on radial and tangential stress are...

I’m trying to minimise the thickness of a rotating disk and I want to know what limitations there are. First it has to be a uniform thickness disk, the rotational speed, the material used and the basic geometry of the disk are known (apart from thickness). Are there any direct relationships...
