C$3$H$8$O is burned with air in a system for heat. The alcohol burns perfectly with air being fed to create pure CO$2$ and H$2$O$,$ and it enters the system at a rate of $3\mathrm{.}30$ kg$/$hour$.$ a$.$ Draw and balance the system.b$.$ Then, to ensure clean burn, a $6\%$ overfeed of air is used. What is your recommended volume feed rate of air to achieve the heat required for this system? Note any assumptions.
