As per the given data:
Volume of saturated steam (V)=0.03 m3.
At pressure (P)=17 bar=1.7 MPa
From steam table,
The specific volume (Vg)=0.11667 m3/kg.
The specific Entalpy (hg)=2794.5kJ/kg
Mass of steam(M)=
Therefore , Enthalpy (H)=m hg=0.257x2794.5 kJ=718.75 KJ
Since steam is saturated, it doesn't contain any liquid phase, therefore it's dryness is 100% and it's quality (x)=1.
