Hydraulics

"Hydraulics is when force is applied to a confined fluid, the change in pressure is transmitted equally to all parts of the fluid."(Jones 91)



Pressure on Moving Fluids

Resources

Transmitting Pressure in a Fluid Force-is a push or pull exerted on an object.(Jones235) Fluids- a material the can easily flow(235)

The more room the fluid has to flow, the more pressure the fluid has. The less room a fluid has to flow, the less pressure it has. ("Pressure on Moving Fluids")


Variation in Fluid Pressure

**Water pressure increases as depth increases."** (Kahan)

**Fluid Pressure (Definition)**

We define the fluid P to be equal to the weight density w times the depth of the fluid h.


 * P = wh ||

The pressure is equal in all directions Since
 * 's Principle**

force Pressure = area

we have

What is Pressure?
 * F = PA ||

="Pressure is the force exerted over an area on the surface of an object" ( Jones74) =
