Arigid, 12-l steam cooker is arranged with a pressure relief valve set to release vapor and maintain the pressure once the pressure inside the cooker reaches 150 kpa. initially, this cooker is filled with water at 175 kpa with a quality of 10 percent. heat is now added until the quality inside the cooker is 40 percent. determine the minimum entropy change of the thermal energy reservoir supplying this heat. use steam tables. the minimum entropy change of the thermal energy reservoir is?
