Enthalpy Calculations in Thermodynamics by Glenn Ray Erasmo is a document available to read on EtoBox.

Here are the key steps to solve this problem: * Given: 1 kg water at 1 MPa, liquid is 1/3 volume, vapor is 2/3 volume * At 1 MPa: hf = 511.6 kJ/kg, hg = 2671.6 kJ/kg, hfg = 2160 kJ/kg * Let x = quality * Then: (1-x) = 1/3 and x = 2/3 * Using mass balance: x + (1-x) = 1 * Solving for x: x = 2/3 * Using energy balance: hmix = xhg + (1-x)hf * Substitute values:
