G A 4-L pressure cooker has an operating pressure of 175 kPa. Initially, one-half of the volume is filled with liquid and the other half with vapor. If it is desired that the pressure cooker not run out of liquid water for 70 min, determine the highest rate of heat transfer allowed. The properties of water are vf = 0.001057 m3/kg, vg = v2 = 1.0037 m3/kg, uf = 486.82 kJ/kg, ug = u2 = 2524.5 kJ/kg, and he = 2700.2 kJ/kg.
