Question

10.3) A commercial oil-fired furnace is rated at 300,000 kJ/h input and uses No. 2 fuel oil. An atomizing nozzle is used with a pressure of 700 kPa and a flow coefficient of 0.8 (Aeff- 0.8A) Find the fuel flow rate and the diameter of the nozzle. Use the data given in Table 2.7 for the properties of No. 2 fuel oil.
