$100mo\frac{l}{s}$ of butane $(C_4{H}_{10})$ gas at $25C$ is completely burned with $2856mo\frac{l}{s}$

air $(21$mol$\%O_2$ and $79$mol$\%N_2)$ at $300C.$ The flue gas leaves the furnace at

$1000C$ which composed of $100mo\frac{l}{s}{O}_2,2256mo\frac{l}{s}{N}_2,300mo\frac{l}{s}C{O}_2,$ and

$400mo\frac{l}{s}{H}_{2}O.$ Determine the amount of heat $($in $MW)$ released from the

combustion process, assuming no heat loss from the burner. The heat capacities

are given below in $k\frac{J}{m}ol.C$ :

$C{p}_{C_4{H}_{10}(g)}=68\mathrm{.}032{10}^{-3}+22\mathrm{.}59{10}^{-5}T-13\mathrm{.}11{10}^{-8}{T}^2$

$C{p}_{O_{2(g)}}=32\mathrm{.}1{10}^{-3}$

$C{p}_{N_2(g)}=30\mathrm{.}6{10}^{-3}$

$C{p}_{C{O}_2(g)}=50{10}^{-3}$

$C{p}_{H_{2}O(g)}=37\mathrm{.}5{10}^{-3}$

$C{p}_{H_{2}O(l)}=75\mathrm{.}4{10}^{-3}$
