3. A stream of liquid -pentane flows at a rate of 50.4 L/min into a heating chamber, where it evaporates into a stream of air 15% in excess of the amount needed to burn the pentane completely. The temperature and gauge pressure of the entering air are 336 K and 2.06atm. The heated gas flows into a combustion furnace in which a fraction of the pentane is burned. The product gas, which contains all of the unreacted pentane and no CO, goes to a condenser in which both the water formed in the furnace and the unreacted pentane are liquefied. The uncondensed gas leaves the condenser at 275 K and 1 atm absolute. The liquid condensate is separated into its components, and the flow rate of the pentane is measured and found to be 3.175 kg/min. (Pentane density =626kg/m³, molecular weight of pentane 72kg/kmol, 1Litre=0.001 m³, R-8.314 (m³Pa)/(mol.K)). Calculate the following items; (a) The molar flow rate of condensed pentane (kmol/min) (b) The molar flow rate of pentane feed (kmol/min) (c) The fractional conversion of pentane achieved in the furnace (d) The molar flow rate of generated CO2 (kmol/min) (e) (f) The molar flow rate of condensed H₂O (kmol/min) The molar flow rate of theoretical O₂ for burning (kmol/min) (g) The molar flow rate of fed O₂ (kmol/min) (h) The molar flow rate of excess O₂ (kmol/min) (i) The molar flow rate of fed N₂ (kmol/min) (j) The molar flow rate of fed air (kmol/min) (k) The volumetric flow rate of fed air (m³/min) (1) =E The total molar flow rate of noncondensed gas (kmol/min) (m) The volumetric flow rate of noncondensed gas (m³/min) C5H12802 5CO2 + 6H2O Noncondensed gas 275K, 1atm (absolute) N₂ ...kmol/min NO n(kmo ...kmol/min min Co ....kmol/min CH₁₂ (liquid) 50.4 L/min n,(kmol/min) chamber 早 n.(kmol/min) 15% excess air 366K, 2.06atm (Pauge) N₂.................. =. .....kmol/min .....kmol/min condenser CH₁₂ (liquid) 3.175 kg/min. =................./min H₂O (liquid) ................mol/min.
