Hello Marta,

Alright, so the principle you want to use is similarity/similitude and model testing.

You may be familiar with Buckingham's Pi Theorem, you should perform that analysis. As a refresher, or if it's your first time, please refer to this document, Example 2:

Please let me know if you need additional help setting up your problem/parameters.
