You should use the steam table that matches the state of water for the values given. Usually, the table wi span the values in the problem. If the state is saturated or two-phase, decide if the saturation pressure or saturation temperature table is more convenient.

Explanation / Answer

Here You should use following tables:

1) Saturated Temperature Table-A as S is same as specific entropy of steam at 255 C saturated steam

2) Compressed Liquid Table-D as V is less than saturation volume for the liquid at 8 MPa

3) Superheated Steam Table-C as H is more than specific enthalpy of steam at 250 C saturated steam

4) Saturated Pressure Table-B as S is in between the entropy of saturated liquid and steam at 10 MPa. Wet steam

5) Saturated Pressure Table-B as V is in between the entropy of saturated liquid and steam at 3 MPa. Wet Steam
