Calculate the rate (kg/h) at which the steam is produced and the volumetric flow rate of the produced steam by using steam tables if a boiler furnace is used to produce steam. The combustion in the boiler furnace produces 1000 kW of thermal energy, of which 57% is transferred as heat to boiler tubes that pass through the furnace. Water enters the boiler tubes as a liquid at 25 and leaves the tubes as saturated steam at 30 bar absolute
