Feed water enters a steam boiler at $10$ bar pressure and $80\backslash$deg C and the mass The flow rate is $50000$ kg$/$h$.$ Since saturated steam is produced from this steam boiler at $10$ bar pressure, If the heat losses from the steam boiler are $300$ kW$,$ the heat that must be provided to the steam boiler with fuel is What is the amount? What are the volumetric flow rates at the steam boiler inlet and outlet?
