A fuel oil is burned with air in a boiler furnace. The combustion produces 869 kW of thermal energy, of which 70.0% is transferred as heat to boiler tubes that pass through the furnace. The combustion products pass from the furnace to a stack at 550 °C. Water enters the boiler tubes as a liquid at 50.0 °C and leaves the tubes as saturated steam at 20.0 bar. Physical Property Tables Property Tabulation Use the steam tables to determine the following properties. Use liquid at the triple point as the reference. Enthalpy of liquid water at 50.0 °C: i kJ/kg Temperature of saturated steam at 20.0 bar: i °℃ Specific volume of Enthalpy of saturated i kJ/kg saturated i m³/kg steam at 20.0 bar: steam at 20.0 bar: eTextbook and Media Hint Save for Later Steam Output Estimate the mass and volumetric flow rates of the steam using steam-table data. m = i Hint kg/h i m³/h Save for Later Ideal-Gas Flow Rate Attempts: 0 of 3 used Submit Answer Calculate the specific volume of the steam for ideal-gas behavior and use that together with the previously calculated mass flow rate to determine the volumetric flow rate of the steam. = i Hint m³/h
