I have been trying to derive an equation to represent how a bag full of fluid would react when dropped dependent on the fluids viscosity. Basically i have the general impulse equation: F∂t=∂P but the time is dependent on the fluids viscosity (higher viscosity the longer it takes for the impact to finish) so I tried using the equation of viscosity: η=F/A*t but in this case of the equation I have a changing area that is dependent on the time as well as the dimensions of the bag. I don't have the slightest idea how to model this varying area since it is an nonuniform shape. Anyone have any ideas how to model this?(adsbygoogle = window.adsbygoogle || []).push({});
