Task B

A Carnot cycle is conducted on steam as follows. The evaporator produces dry saturated steam at $10$ bar. The steam is expanded reversibly and adiabatically in a turbine to $1$ bar. The exhaust steam is partially condensed and then compressed back to $10$ har. As a result of the compression, the wet steam is changed completely into saturated water.

Assuming a flow rate of $\backslash (1\backslash$mathrm$\{$~kg$\}/\backslash$mathrm$\{$s$\}\backslash )$ throughout determine the condition and specific enthalpy at each point in the cycle.

Calculate the energy transfers for each stage.

Show that the efficiency is correctly predicted by the expression, $\backslash (\backslash$eta$=1-$T$\_\{\backslash$text $\{$cold $\}\}/$ T$\_\{\backslash$text $\{$hot $\}\}\backslash )$
