1- 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 has poor insulation and loses 100 kW of heat to the environment, calculate the time required to increase 1 ton of water to 150 ° C in the boiler.
