Calculate damping coefficient of dashpot from physical dimensions

AI Thread Summary
To calculate the damping coefficient of a linear viscous dashpot, the physical dimensions of the piston and the dynamic viscosity of the damping fluid are essential. A user seeks the specific equation used by an online calculator for this purpose. The general equation of motion for a single degree-of-freedom system with viscous damping is referenced as a potential resource. However, the user emphasizes the need for an equation that incorporates the physical dimensions rather than performance data. Accessing the source of the referenced webpage may reveal the required equation.

Hi all,

I am trying to calculate the damping coefficient of a linear viscous dashpot/damper given the dimensions of the piston, and the dynamic viscosity of the damping fluid.

I have found this calculator, but does anyone know the equation that it uses?

Many thanks,
JJ.

Thanks, I was more looking for an equation(s) which allows me to input the physical dimensions of the piston and the viscous fluid in order to calculate the damping coefficient, rather than recorded data of the damper performance.
 
View the source of the web page and you should be able to see the equation used.

My water meter is submerged under water for about 95% of the year. Today I took a photograph of the inside of my water meter box because today is one of the rare days that my water meter is not submerged in water. Here is the photograph that I took of my water meter with the cover on: Here is a photograph I took of my water meter with the cover off: I edited the photograph to draw a red circle around a knob on my water meter. Is that knob that I drew a red circle around my meter...

Thread 'Questions about the Tesla turbine'

Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...
