#$2$ ONLY PLEASE

$01.$ Hot exhaust at $527C_{?}$ is released from a metal processing plant into the atmosphere.

An engineer proposes to convert the "wasted" heat to electricity by building a heat engine

connected with a generator. The ambient temperature and pressure are $27C_{?}$ and $\frac{1}{b}ar{?}_{(}),$

respectively.

Calculate the highest, theoretically possible energy conversion efficiency $($in $\%)$ for

converting the wasted heat to electricity. $($In other words, this should be the theoretical

maximum efficiency that no energy conversion system can exceed for the conditions given.$)$

Question $2$

For Problems $2$ and $3,$ consider a Brayton cycle with air as the working fluid with constant $$

$=1\mathrm{.}4$ and gas constant $=287\frac{J}{k}g.K,$ where $I_{{?}_{?}}(amb)=15C,P_{{?}_{?}}(amb)=\frac{1}{b}ar,$ pressure ratio of $25,$

and maximum cycle temperature, $I_{\text{m}\text{a}\text{x}}=1527C.$

P$02.$ Assuming ideal operation, Calculate the compressor exhaust temperature $($in $C).$
