Propane (C₂H₂) is burned in a combustion chamber at a flow rate of 30.00 m³/min with 30.0% excess air. If the propane and air streams enter the chamber at 21.0 °C and 1.15 atm (absolute), and the products leave the chamber at 270.0°C and 3.20 atm (absolute), what is the volumetric flow rate of product gas from the chamber? Assume 100% conversion and ideal behavior. To solve for the flow rate, first label the process flow diagram. Label any quantities as "unknown" if they are not given or implied and "none" if the quantity is zero. Do not leave any blank spaces. Variable names are given for reference later.
