$4.)15$ points

a$)$ How much entropy was generated in pumps in problem $3?$ Explain your answer.

b$)$ For problem three assume the source is at $550^($@$)$C$,$ the sink at $20^($@$)$C and the receiver for the process heat is at

$35^($@$)$C$,$ Determine the rate of entropy generation for this process.

c$)$ Determine the efficiency of the co$-$generation plant analyzed in problem $3.$

d$)$ How would the real cogeneration plant compare to the one analyzed in problem $3,$ and state your reasoning?
