Required information

A flue gas is cooled from $950C$ to $150C,$ and the heat is used to generate saturated steam at $100C$ in a boiler. The flue

gas has a heat capacity given by

$\frac{C_P}{R}=3\mathrm{.}83+0\mathrm{.}000551\frac{T}{K}$

Water enters the boiler at $100C$ and is vaporized at this temperature; its latent heat of vaporization is $2256\mathrm{.}9k{J}^{-1}k{g}^{-1}.$ Take

$R=8\mathrm{.}314J*mo{l}^{-1}*K^{-1}.$

NOTE: This is a multi$-$part question. Once an answer is submitted, you will be unable to return to this part.

With reference to a surroundings temperature of $25C,$ what is the lost work of this process in $kJ*mo{l}^{-1}$ of flue gas?

The lost work of this process is

$kJ*mo{l}^{-1}.$A flue gas is cooled from $950\backslash$deg C to $150\backslash$deg C$,$ and the heat is used to generate saturated steam at $100\backslash$deg C in a boiler. The flue gas has a heat capacity given by
