Question $2$

An ideal diesel engine has a compression ratio of $20$ and uses air as the working fluid. The state of air at the beginning of the compression is $95$ kPa and $20C.$ If the amount of heat addition during the constant pressure process is $150k\frac{J}{k}g,$ using the air standard assumption determine:

a$.$ The maximum temperature of the cycle

b$.$ Cut$-$off ratio $(r_c)$ of the cycle

c$.$ The thermal efficiency of the cycle

d$.$ Worknet produced by the cycle

e$.$ The mean effective pressure $($MEP$)$ of the cycle

Note: $C_p=1\mathrm{.}005k\frac{J}{kgK},C_v=0\mathrm{.}718k\frac{J}{kgK},R=C_p-C_v[k\frac{J}{kgK}],k=\frac{C_p}{C_v}$
