## What unit is used in honor of Evangelista Torricelli?

The torr (symbol: Torr) is a non-SI unit of pressure defined as 1/760 of an atmosphere. It was named after Evangelista Torricelli, an Italian physicist and mathematician who discovered the principle of the barometer in 1644.

How do you derive Torricelli’s equation?

Torricelli’s Law Derivation

1. v²/2 + gh p/ρ = constant.
2. v is speed of liquid,
3. g denotes gravitational acceleration,
4. h shows liquid’s height over reference point,
5. ρ is density.
6. P is equal to atmospheric pressure at the top of the container.
7. V = √2gh.

### What is Torricelli’s theorem in fluid mechanics?

Torricelli’s theorem, also called Torricelli’s law, Torricelli’s principle, or Torricelli’s equation, statement that the speed, v, of a liquid flowing under the force of gravity out of an opening in a tank is proportional jointly to the square root of the vertical distance, h, between the liquid surface and the centre …

What is Torricelli vacuum?

[¦tȯr·ə¦chel·ē·ən ′vak·yəm] (fluid mechanics) The space enclosed above a column of mercury when a tube, closed at one end, is filled with mercury and then placed, open end downward, in a well of mercury; this space is evacuated except for mercury vapor.

What is Torricelli barometer?

The first mercury filled glass tube was generally accepted to have been invented in 1643 by Torricelli, which became known as Torricelli’s mercury barometer. In this he produced a vacuum by filling a glass tube with mercury, inverting it and then submerging the open end in a vessel of mercury.

## When can you use Torricelli’s equation?

In physics, Torricelli’s equation, or Torricelli’s formula, is an equation created by Evangelista Torricelli to find the final velocity of an object moving with a constant acceleration along an axis (for example, the x axis) without having a known time interval.
