A pressure cooker with volume V contains a two-phase liquid-vapor mixture of water with quality a and pressure Pa. It is heated with thermal energy Qab until the pressure reaches Pb, where it remains a liquid-vapor mixture with quality . Find the specific internal energy after heating, ub, if V = 0.011 m3 a=0.1,Ta=95.0C and Qab=26.45 kJ.
