## What is Torricelli?

Torricelli's Theorem Calculator
Based on Torricelli's Law, also known as Torricelli's Theorem, this calculator is a tool in fluid dynamics that relates the speed of fluid flowing out of an opening to the height of the fluid above the opening.

Features:
• Input parameters such as Tank Height, Tank Radius, Spigot Height, and Spigot Radius.
• Simulate water flowing out from the tank in 3D.
• Simulate the volume of water remaining over time.
• Simulate water pressure over time.
• Simulate water speed at the spigot over time.
• Simulate water distance over time.
• Simulate the farthest water height remaining over time.
• Simulate the time needed for the water to flow out until reaching the spigot height.
• Works seamlessly on both iPhone and iPad.
• Lightweight, compact app optimized for everyday use.
• Ad-free and built with privacy in mind.

Torricelli's Theorem states that if a tank contains liquid and is open to the atmosphere at its top, and there is an orifice in the tank at a height h below the top of the liquid, then the speed of outflow from the orifice is √2gh, provided the liquid obeys Bernoulli's equation and the top of the liquid can be regarded as motionless.

Torricelli's Theorem Formula:
v = √2 * g * h
where:
v : Fluid Speed at the Orifice, in meters per second (m/s)
h : Height of the Orifice from the Top, in meters (m)
g : The acceleration due to gravity, 9.80665 m/s²
