H2

O undergoes a cycle that is made up of four separate processes. The mass of the

H2

O is 4 kg and each process is described below.

Isobaric Process State 1 to State 2:

State 1:

= 2.8 bar,

= 0.34

State 2: Saturated vapour

Isometric Process State 2 to State 3

State 3:

= 5 bar

Isobaric Process State 3 to State 4:

Isometric Process State 4 to State 1:

(a)  Draw the cycle on a T − Vdiagram.

(b)  Calculate V

(in m

3

).

(c)  Calculate the work done from State 1 to State 2. ( →

).

(d)  Calculate the heat transfer from State 2 to State 3. (

).

(e)  Calculate the dryness fraction at state 4. (

)

(f)  Calculate the heat transfer from State 3 to State 4. (

).
