Flow Work and Flow Energy - thermodynamics:

Flow Work: The flow work is energy needed to move the working substance against its pressure

It is called as flow or displacement energy.

It working substance with pressure p, flow  through area A, (m2) and moves throughout distance x. (m) work required to move working substance.

Flow work = force X distance = (P.A).x = PV Joule

Flow Energy: Flow work analysis is based on consideration that there is no change in PE, KE, U. But if these energies are considered in flow process, the flow energy per unit mass can be expressed as

E = F.W + KE + PE + I.E.

Eflow  =  PV + V2/2 + gZ + U

= (PV + U) + V2/2  + gZ

E = h + V2/2 + gZ
