Q$1.$A$)(30\%)(6$marks$)-$I$)$ Determine the inlet temperature of the benzene if

$1\mathrm{.}66$kmol$\frac{e}{m}in$ of benzene enters a heat exchanger at $1\mathrm{.}4$atm and leaves at $140C$ as

superheated vapor and a total heat of $1410kW$ is supplied to the heat exchanger. II$)$

What would be the pressure if the Tsat$=110C$ for the same $Ti$ and Tout as above,

Calculate the new

$45\mathrm{.}152k\frac{J}{m}ol$

$Ln(P_{\text{s}\text{a}\text{t}})=13\mathrm{.}79+(\frac{2727}{t_{\text{s}\text{a}\text{t}}+218}),tinC,Pin$ kPa,$1$atm$={10}^{5}Pa$
