A rigid closed vessel is initially filled with 2 kg of water which is a mixture of saturated liquid and saturated vapor states at 2 bar. The vessel is placed in an oven which heats the mixture to the critical state. Using the saturated and critical property values from the table given below, the heat transferred from the oven to the vessel is __________kJ. Pressure = 2 bar vf (m3/kg) vg (m3/kg) uf (kJ/kg) ug (kJ/kg) 0.0010605 0.8857 504.49 2529.5 Critical pressure vc (m3/kg) uc (kJ/kg) 0.003155 2029.6
