Fatique Testing

Fatique Testing

Fatique Testing

(OP)
I have been asked to determine the velocity/range of velocities during cycle testing in order to size the pump required.

The specs are as follows amplitude varies from 0-500 psi frequency varies from .5 to 30 hz. The pressure and frequency will be set by the end user depending on his/her test requirements.

I am not sure what governing equations to use. If someone could help guide me I would greatly appreciate it. Thank you.

What flowrates you need?

The flowrate does not matter as long as we can provide the pressures.  

RE: Fatique Testing

Then your pump will be very small.

What are the equations I need to use?
 

RE: Fatique Testing

Flowrate = Volume_of_fluid_needed / Available_Time_to_fill

RE: Fatique Testing

Try picking up a Crane Technical Paper 410, "Flow of Fluids."  It has all the equations you will need ... and then you might be able to figure out BigInch's comment about flowrates. (hint, you haven't come close to giving anyone enough information to otherwise help you.)

i understand what flowrate is. That is not what I was looking for. I found what I needed.

Thank you.

RE: Fatique Testing

Good, because I don't think we could tell what you were looking for.
