Question
An ideal Diesel cycle with air as the working
fluid has a compression ratio of 14 and a
cutoff ratio of 3. At the beginning of the
compression process, the working fluid is at
110 kPa, 30°C. Determine the temperature
and pressure of the air at the end of each
process, the net work output per cycle
[kJ/kg], and the thermal efficiency.
Note that the nominal specific heat capacity
values used for air are Cv =1.00 kJ/kg.K; Cv
= 0.717 kJ/kg.K; k = 1.4 and R = 287 J/kg.K
