Problem No: $2$ The compression ratio in an air$-$standard Otto cycle is $9.$ The pressure and the temperature at the beginning of the compression stroke are $1$ bar and $300$ K $.$ The heat supplied during the constant volume process is $\backslash (24\backslash$mathrm$\{$MJ$\}/\backslash$mathrm$\{$kmol$\}\backslash ).$

a$)$ Calculate the net work output of the cycle

b$)$ Calculate the thermal efficiency of the cycle
