For Problems $4$ to $6,$ 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 $I_{\text{a}\text{m}\text{b}}=27C,$ and maximum cycle temperature,

$I_{\text{m}\text{a}\text{x}}=1700C.$

P$04.$ Calculate turbine exit temperature $($in $K_{?}),$ assuming ideal operation, if compressor exit

temperature is $700$ K$.$ Pay attention to UNITS.

Question $5$

P$05.$ Choose one of these four choices: How would turbine exhaust temperature $($in

Problem $4)$ change if the compressor exit temperature is increased from $700$ K $?$ Assume

ideal operation.
