Determining fluid flow in a closed system.
Determining fluid flow in a closed system.
(OP)
I have a tool that uses external hydrostatic pressure and internal fluid pressure to move a piston.( In static equilibrium) I have 2 check valves inside that allow the transfer of fluid internally from one chamber to another. I also have another regulated valve internally that allows .1gpm to flow from the check valves. The external forces acting on the tool is around 15000 lbf. My question is, How do I calculate the velocity the fluid will flow through the tool with the check valves and regulator valve? The internal piston moves through the fluid with only the pressure build up from the resistance of the check valves and regulator valve.

unknown= velocity due to these external forces acting across a piston onto internal fluid pressures across a 1" piston.

in your .281 hole its 10,5 m/sec, say 35 ft/sec
In your 1" piston it's 1.2 m/sec - 4 ft/sec
A sketch would really really help though....

Never heard of a mechanical engineer disavow knowledge of fluid statics and dynamics.

doing it too late last night - divide my answers by 60 as I forgot to change gpm into seconds.
velocity in your .281 hole is 0.168 m/sec
velocity in the 1" cylinder is 0.02 m/sec, but please check my calcs....

Glad to help you out, I think....
