Liquid ethanol (CHO) enters a furnace at a flow rate of 1 L/min. Oxygen is fed to the process in an air stream at 20% excess at a temperature of 25 °C and a pressure of 1 atm. Assume ideal gas behavior. The specific gravity of ethanol is 0.79 and its molecular weight is 46.1 g/mol. a. What is the molar flow rate of ethanol and air into the furnace? (A:290mol/min air) b. What is the volumetric flow rate (in m/min) of the air into the furnace? (A: 7m/min air) c. Balance the process assuming complete combustion. All products are in the gas phase. (You must determine the molar flow rate of all components in the product stream) A: 10 mol/min 02) d. If the air enters the process in a pipe that has a 50 cm cross-sectional area, what is the required pipe diameter (in cm) to keep the outlet velocity the same as the inlet? Assume that the outlet gas leaves at a temperature of 1000 °C and a pressure of 1 atm. (A: 17 cm)
