Entropy is a measure of irreversibility or disorderness of a
system. All actual thermodynamic processes are irreversible
and their amount of irreversibility is measured by change in
entropy.

Answer / ak

Entropy is always associated with heat transfer between 2 bodies....it is ratio of heat transfer and temp....so if a body is rejecting heat its entropy is decreasing and if a body is gaining heat then its entropy is increasing...

Answer / archana

Entropy defines weather a cycle is reversible or irreversible

Answer / vny

actually entropy doesn't have any significance, we always defined change in entropy of a substance.. entropy generally defines the amount of internal energy gain or heated by the source on increasing temperature...
it is a state function i.e. its only depend on the intial and final postion of the body...

ex. heating or cooling of matter

Q : How to calculate cooling water pumps head, do I need to consider static head and frictional loss of the pipe with high elevation? I mean to say is discharge pipe branches to several elevations and joins to the cooling water return line. The highest elevation pipe goes to a heat exchanger at (xx) psi inlet pressure. Should I consider only pump discharge header and this piping for head calculations? How about frictional losses in return pipe? Pressure recovered in return piping is good enough to make it back to the cooling tower?
