Principle	Description
Pressure Uniformity	If the weight of a fluid is neglected, the pressure throughout an enclosed volume will be the same
Pressure Direction	The static pressure in a fluid acts equally in all directions
Pressure Perpendicularity	The static pressure acts at right angles to any surface in contact with the fluid
Force Equation	F = p × A (Force = Pressure × Area)
Jack Principle	Fs / As = Fl / Al (Pressure is equal in both cylinders)
