QUESTION $3$

$($PO$2,$ CO$2,$ C$4)$

A system containing $2\mathrm{.}5$ kg of water undergoes a thermodynamic cycle. The system, initially at $\backslash (185^\{\backslash$circ$\}\backslash$mathrm$\{$C$\}\backslash )$ and $550$ kPa is heated at constant volume to $1100$ kPa $.$ Following that, the system undergoes isobaric process until water turns into saturated vapour. Then, the system is subjected to cooling in such a way that the volume remains unchanged. Finally, the system is isothermally expanded by receiving heat at $1015\mathrm{.}8$ kJ to its initial state.

a$)$ Using a graph paper, draw T$-$v and P$-$v diagrams showing all values at each state.

b$)$ Assuming both $\backslash (\backslash$triangle $\backslash$mathrm$\{$KE$\}\backslash )$ and $\backslash (\backslash$triangle $\backslash$mathrm$\{$PE$\}\backslash )$ are negligible, determine the heat transfer and work for each process involved. Show all calculations clearly.

c$)$ Using one example, discuss the difference between isothermal and adiabatic process
