Oh sorry I am new to this forum and I may made a mistake :D The task or homework is to discribe the volume of the balloon and not the airflow. And I tried to solve this a few times but I can't come up with a suitable solution.

I have a problem. The task is to develop an differential equation of the airflow of a balloon. I know that it is dependent on the volume and pressure. But I can't get a good differential equation. Can someone help me? [Thread moved from the technical forums, so no Homework Help Template is shown]
