|
Pascals Principle |
changes of pressure on the surface of a confined fluid are exerted equally throughout the fluid and at all points on the fluid's container |
|
|
hydraulics |
science of the transmission of forces and energy by liquids |
|
|
IMA = Al/Ae |
IMA = load piston area/effort piston area |
|
|
venturi |
specially designed constriction in a pipe, to measure fluid flow rate by comparing the differences in fluid pressure before and within the constriction that occur according to Bernoulli's principle |
|
|
Henri Marie Coanda |
Romanian aerodynamics engineer who invented the first jet engine and discovered the principle of aerodynamic lift that bears his name |
|
|
Coanda effect |
fluids flowing close to a curved surface follow the shape of the surface rather than a straight path |
|
|
airfoils |
any surface that is designed to deflect air or create a force as it moves through the air |
|
|
Daniel Bernoulli |
Holland, studied the flow of liquids through pipes of different diameters the ran horizontally and vertically |
|
|
Bernoulli's principle |
flowing ideal fluid: 1. it is incompressible 2. flows smoothly with no turbulence 3. speed of the fluid at a point in the pipe does not change with time 4. friction has no effect on the liquid |
|
|
hydraulic machine |
has different pistons with hydraulic fluid in them |
|
|
cylindrical piston |
cylinder, connected to rod |
|
|
load piston and cylinder |
smooth cylinder in which the piston slides |
|
|
small-diameter cylinder containing another piston |
effort piston and cylinder |
|
|
hydraulic fluid |
low-viscosity oil |
|
|
hydraulic pump |
effort pressure is delivered by this |
