Instructions: $$ Project activity: Evaluation of thermal efficiency & output work of Rankine cycle $$ Form a group of three students and perform the activities $$ Activities to be submitted in a form of report and to be presented in power point $$ A plagiarism report must be submitted along with the report.

Question $1$: Refer to figure $1$ to solve the following: a$)$ The thermal efficiency of the cycle. $(15$ Marks$)$ b$)$ Total turbine net output work $($Wnet$)(5$ Marks$)$

Figure $1$

Question $2$: Refer to figure $2$ to solve the following a$)$ The thermal efficiency of the cycle. $(15$ Marks$)$

b$)$ Total turbine net output work $($Wnet$)(5$ Marks$)$

Notes: $$ Assume the Preh $=4\mathrm{.}5$ bar and the steam is reheated to $600$ C $$ The moisture content of the steam at the exit of the low$-$pressure turbine is not to exceed $9\mathrm{.}5\%$
