Physics 3-2-17 Bernoulli – Part 1

PHYSICS: Were you amazed at the effect of change in surface area on the velocity of water, and especially the pressure of water, flowing through a tube? Thaaaaat explains how a calm ride on a lazy river can turn crazy in just a few seconds!

Here is the lesson from Thursday – Bernoulli Part 1. We mainly concentrated on qualitative applications of Bernoulli’s Principle with some practical applications. More of the quantitative stuff tomorrow!
