Answer Posted / arul - mz
Know the things with pure reasoning and relate to the
subject..
PUMP is a device just used to increase the energy of the
liquid.
As per BERNOULIS Theorem, energy in a liquid in continuous
flow has 3 components pressure, velocity & datum
(potential) head....
The energy developed can be used to
1) increase the Kinetic energy of the liquid
Application: Liquid cooling systems...
2) increase in the datum head or potential energy of the
liquid.
Application: Transfer of water from sump to overhead tank
in our houses.
3) increase in pressure of the liquid.
Application: Hydraulic pumps.
For utilising any of the above mentioned properly, we have
to restrict the changes of energies to other forms.
That requires proper engineering :-)
