Question $3(40p)$ : Steam generated $($stream $2)$ in a power plant at a pressure of $8600$kPa and at a

temperature of $500C$ is fed to a turbine. Exhaust from the turbine $($stream $3)$ enters a condenser at

$10$kPa, where it is condensed to saturated liquid $($stream $4),$ which is then pumped to the boiler

$($stream $1).$ The mass flow rate of the steam is $84\mathrm{.}75k\frac{g}{s}$ and the surrounding temperature is $25C.$

Thermodynamic properties of the streams are given in the schematic diagram of the cycle shown

below. Make the thermodynamic analysis of the system and calculate the thermodynamic

efficiency. $($Fill in the blank fields in the Table $2)$
