Liquid water at 330 K and 7500 kPa flows into a boiler at the rate of 15 kg/s and is vaporized, producing saturated vapor at 7500 kPa. What is the maximum the heat added to the water in the boiler that can be converted into work in a process whose product is water at initial conditions, if To = 300 K? What is the rate of entropy and enthalpy change in the surroundings and in the system as a result of the work-producing process? Where the volume expansivity of liquid water at 330 K is 460 × 106 K-¹
