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,

The general equation of motion for a single degree-of-freedom system with viscous damping can be found here. Hope this helps!

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.
