Reciprocatin Compressor. It is taken in use to compressor gases. (kE2 - kE1) = 0, (pE2 - pE1) = 0
q1-2 - w1-2 = (h2 - h1) + 0 + 0 - q1-2 - (-w1-2) = h2 - h1
w1-2 = q1-2 + (h2 - h1)
Heat gets rejected and work is done on system.
Dirrerent Cases of Sfee
Sfee
1. Boiler
q = h2 - h1
2. Condenser
q = h1 - h2
3. Refrigeration or Evaporator
4. Nozzle
V 2/2 - V 2/2 = h - h
5. Turbine
W1-2 = h1 - h2; WD by the system due to decrease in enthalpy
6. Rotary compressor
W1-2 = h2 - h1; WD by the system due to increae in enthalpy
7. Reciprocating Compressor
W1-2 = q1-2 + (h2 - h1)
8. Diffuser
q - w = (h2 - h1) + ½( V22 -V 2)
