Find phase at given state of water by thermodynamic tables

Question

Determine the phase and the specified property at a given state of water using thermodynamic tables.

a) Pressure (p) = 2.5 bar, specific volume (v) = 0.5 m3/kg, Determine the phase and temperature (T) in °C.
b) p = 20 MPa, T = 573.15 K. Determine the phase and v in m3/kg.
c) p = 10 bar, T = 400 °C. Determine the phase and v in m3/kg.
d) T = 120 °C, quality (x) = 50%. Determine the phase and v in m3/kg.
