#$501.$ Ideal Otto Cycle Process

An ideal Otto cycle has a compression ratio of $9.$ At the beginning of the compression process, $P_1=87$kPa,$T_1=26C,$ and $v_1=0\mathrm{.}004m^3.$ The maximum temperature is $1127C.$ For air, remember that $k=1\mathrm{.}4.$ There are multiple smaller answers to help understand tackling a problem like this.

Consider Process $1->2.$ What is $T_2($the temperature at the end of the isentropic work in process$)?$ number $($rtol$=0\mathrm{.}05,$ atol$=1$e$-08)$

Consider Process $2->3.$ What is $Q_{in}($the heat added$)?$

answer: $[$kJ$]$ number $($rtol$=0\mathrm{.}05,$ atol$=1$e$-08)$

Consider Process $3->4.$ What is $T_4?$

answer: $K$ number $($rtol$=0\mathrm{.}05,$ atol$=1$e$-08)$

Consider Process $4->1.$ What is the magnitude of $Q_{\text{o}\text{u}\text{t}}?$

number $($rtol$=0\mathrm{.}05,$ atol$=1$e$-08)$

Based on the above, what is the net work?

answer: $[$kJ$]$ number $($rtol$=0\mathrm{.}05,$ atol$=1$e$-08)$

Based on the above, what is the thermal efficiency?

answer: $[$fraction$]$

number $($rtol$=0\mathrm{.}05,$ atol$=1$e$-08)$
