A cylinder contains 0.03 m^3 of steam with a dryness fraction of 0.8 at a pressure of 16 bar.

The steam expand during a steady reversible non-flow hyperbolic process until the volume

becomes 0.24 m^3.

With information from the steam tables at 16 bar, for the initial state (state 1):

a) Calculate

i. the specific volume for the initial state

ii. the specific internal energy for the initial state

iii. the specific enthalpy energy for the initial state

iv. the mass of the steam

b) Calculate the pressure at the final state

c) Calculate the specific volume at final state

With information from the steam tables at the final pressure, for the final state (state 2)”

d) calculate

i. the dryness fraction of steam at state 2

ii. the specific internal energy for the final state

iii. the specific enthalpy for the final state

Calculate for the steady non-flow hyperbolic process:

e) the work energy transfer

f) the change in internal energy

g) the heat energy transfer
