Q1) (15 points) A 2.5 lit, 4-stroke, compression ignition engine running at 3000 RPM operates on ideal Dual cycle. The engine is supplied with air at
100kPa
and
17\deg C
. If the compression ratio is 14 , the cut-off ratio is
1.8
, and maximum temperature is 1527 . C, then determine: (Use table A.17, or take average
k,C_(v)
and
C_(p)
)) the net output work of the cycle, in
kW
draw the
T-s
or
P-v
diagram. the total heat added, exergy destructed in the constant volume heat addition process the thermal efficiency of the cycle, the second law efficiency.
