Hi everyone(adsbygoogle = window.adsbygoogle || []).push({});

I'm doing a project which looks at the measurement of astha inhaler spray force. The idea is that a spray will be propelled from an inhaller onto a flat plate and the force will be measured using a load cell for example. To get an intial idea of the size of forces, I am trying to find a mathematic way of determine the force and wondering if you could help. People have suggested calculating spray force by looking at the kinetic energy of a particle or the momentum, but i'm confused on how to do this. How can you mathemtical calculate the force of a plume made up of thousands of particles which atmomise in a matter of seconds.

Thanks

Amit
