ASSUMPTIONS:

$-$ Air is composed of $21\%$ O$2$ and $79\%$ N$2$ by volume

$-$ Air is used for combustion

$-$ Complete combustion occurs

$-$ Nitrogen does not undergo a reaction at the combustor

Considering the above assumtions,

a$)$ Determine the molecular weight of air?

b$)$ Determine the volume $($m$3)$ occipied by $1$ kmol air at normal conditions?

In this combustor, the wood with the given elemental analysis $(50\%$ Carbon, $43\%$ Oxygen, $6\%$ Hydrogen, $1\%$ Nitrogen by weight$)$ is planning to be used as fuel.

Determine: c$)$ Stoichiometric air requirement $($kmol$/$h$)$ if $100$ kg$/$h of wood is to be burned?

d$)$ Stoichiometric air requirement $($kg$/$h$)$ if $100$ kg$/$h of wood is to be burned?

e$)$ The percentage of CO in the flue gas by volume on dry basis?

f$)$ Total air requirement $($in Nm$3/$h$)$ if $20\%$ excess air supplied for complete combustion of $100$ kg$/$h of wood?

Air quality control question!!!and please write elemental combustion reactions
