HW $10(2)-4$: $(10$ points$)$

An ideal Otto cycle has a compression ratio of $8.$ At the beginning of the

compression process, air is at $95$ kPa and $27C,$ and $740k\frac{J}{k}g$ of heat is transferred

to air during the constant$-$volume heat$-$addition process. Determine the total

exergy destruction associated with the cycle, assuming a source temperature

of $2000$ K and a sink temperature of $300$ K $.$ Account for the variation of specific

heats with temperature.

Hint: Reference to EWH $10(2)-4$ which is slightly different from this HW problem.

HW $10(2)-5$: $(4$ points$)$

For the same ideal Otto cycle in HW $10(2)-4,$ determine the total exergy destruction

associated with the cycle using constant specific heats at room temperature $(25C).$

$($Write down generic equations used and your calculation steps$)$

$10(2)-5$ is what needs answered but it relys on $10(2)-4$
