Question 21
XE-ENAT2 marksNeeds review
A rigid tank contains 1.0 kg of pure water consisting of liquid and vapour phases in equilibrium at 10 bar. If the liquid and vapour phase each occupies one half of the volume of the tank, then the net enthalpy of the contents of the tank is ______ kJ (1 decimal place).
For saturated liquid and vapour at 10 bar, the thermodynamic data table provides the following value:
v_f = 1.127 × 10⁻³ m³/kg, v_g = 194.3 × 10⁻³ m³/kg,
h_f = 762.6 kJ/kg, h_g = 2776.2 kJ/kg
