A Lesson on Hydraulics and Pneumatics with Heron JULIA FARRY
What is hydraulics and pneumatics?
Boyles Law For a fixed mass of a gas at constant temperature, the volume is inversely proportional to pressure.
Boyles Law Mathematically 1 ?or P =? ?where k is ? some constant.
The Graphic Representation <- Plot of Volume against Pressure Pressure Plot of Volume against Pressure -> 1/Pressure https://socratic.org/questions/how-do-you-graph-boyles-law?source=search
Kinetic Theory of Gas https://www.grc.nasa.gov/www/k-12/airplane/kinth.html
Pressure on a Microscopic Level This idea has been converted into an equation that helps us find the force a fluid applies on a container. ? =? ? Remember Area of a Circle = ??2 Circumference of a Circle = 2??

Incompressibility of Water applied in Hydraulics
A Combination of Hydraulics and Pneumatics: Heron s Fountain This fountain was first constructed by an inventor and mathematician by the name Heron of Alexandria in 1st century AD. Can anyone describe what they predict will happen when I put water in Basin A, and why?
Law of Conservation of Energy Energy can neither be created nor destroyed but is transferred. What is doing the work then?
