Physics Exercise-Santa Monica College .

 
Objective: Estimate v1 (how fast the water leaves from the hole). You can use a water bottle, styrofoam, cup, etc. to replicate the example but instead of assuming v2=0, you need to figure out how to experimentally estimate v2, derive the appropriate expression for v1, and then estimate v1. The hole can be made at any height you like, and you can choose the respective diameter accordingly.
Repeat the experiment 5 times, document all experimental values such as the dimensions of the bottle, water level, times, etc.p
