3. 1 ton of water per hour at 35°C and 2000 kPa enters the boiler. The wet steam exits the boiler at 2000 kPa. The wet steam then enters a throttling valve (expansion valve) and exits the throttling valve at 101.325 kPa and 125.5°C. What is the quality of wet steam at 1500 kPa? What is the temperature of wet steam? How much is the heat duty of the boiler (in kW)? You cannot assume that the steam / liquid water is ideal gas.
