At steady-state, fuel oil is supplied at 0.01 gal/min to an oilfurnace for home heating. (Note: 1 gal = 3.785*10^-3 m^3). The fueloil density is 870 kg/m^3. Combustion air at 65°F and 1 atm entersthe furnace with a volumetric flow rate of 15.2 ft^3/min. Determinethe mass flow rate of combustion product gases flowing up thechimney flue. Also, determine the average velocity of the flue gasif the gas temperature is 225°F and the flue diameter is 9 in.Assume that the flue gases behave as an ideal gas with an apparentmolecular weight of 29 kg/kmol. Also, assume that the pressure inthe flue is essentially 1 atm (absolute).
