A rigid, 75-liter steam cooker is arranged with a pressure relief valve set to release vapor and maintain the pressure once the pressure inside the cooker reaches 200 kPa. Initially, this cooker is filled with water at 200 kPa with a quality of 8 percent. Heat is now added until the quality inside the cooker is 59 percent. Determine the minimum entropy change of the thermal energy reservoir supplying this heat. Round all your intermediate calculations and your answer to four decimal places.
