So I am trying to calculate the damping coefficient of air passing around a piston that is oscillating in a tube. The idea is completely theoretical. I dont have any real data.(adsbygoogle = window.adsbygoogle || []).push({});

As far as i understand:

1. The viscous sheer stress = mu.du/dy

2. Therefore the viscous sheer force = (piston surface area)*mu.du/dy

But this is not the damping coefficient. How do I calcualte the damping coefficient?
