same as the equation for free fall of an object from an initial velocity of zero. (slide 12)
Summary of Torricellis equation
If you have a tank of fluid and there is a small hole in the bottom of the tank,
the fluid will leave through that hole with the same velocity
it would have if you dropped it from the top of the tank to the level of the hole.
Graph of Torricellis Equation
If we plot v2 vs. the square root of the height
We get a straight line through the origin
The gradient will be equal to the square root of 2 g.
