Water vapor at a flow rate of 20000 kg / hour enters a steam boiler with a specific volume of 150 kPa 0.001053 m3 / kg. With the energy it takes from the fuel in the combustion chamber of the boiler, it rises at 150˚C at 1200 kPa. If the boiler is badly insulated and loses 500 kW of heat to the environment, calculate the time required to increase 1 ton of water to 150 ° C in the boiler.

Steam generators are a type of heat exchanges that are used in power plants to generate steam at desired pressure and temperature (Fig. Q1.b). In a steam generator, saturated liquid water at 30°C enters a 60-mm diameter tube at the volume flow rate of 12 L/s. After exchanging heat with hot gas, the water changes to steam and leaves the generator at a pressure of 9 MPa and a temperature of 400°C. During this process, the diameter of the water/steam tube does not change.(i) Calculate the steam mass flow rate.
