Pressure Head : The height of fluid necessary to produce a pressure, p
Velocity Head: The vertical distance needed for the fluid to
start from rest and to fall vertically and reach velocity V.
Elevation Head: The potential energy of fluid
Statics Pressure: The actual thermodynamic pressure of a fluid as it flows [2]
Dynamic Pressure: The pressure caused by the velocity of
fluid. This pressure is measured if all the Kinetic energy is
converted to mechanical energy
Hydrostatic Pressure: It represents a change in pressure due to
elevation change
Applied to the motion of particle in an ideal fluid
Properties of ideal fluid:
Inviscid, loses no energy
to friction
Application
Siphon [1]: Siphon is a bent used to
transfer a liquid over an obstruction to
a place at lower elevation without the
use of pumps. Siphons operate using
atmospheric pressure. Liquid flows
from high pressure region to low
pressure region. Therefore, the liquid
on the upper container flows into the
flask at lower level under atmospheric
pressure.
