Evaluate mechanical work in different steady flow process:

Work done by steady flow process

and work done in non flow process,

1. Constant Volume Process; W1-2 = V(P1 - P2)

Steady flow equation

dq =  du =  dh +  d (ke) +  d (pv)

Now h = a + pr

By differentiating

dh =  du +  dtper

=  du =  pdv =  vdp.
