Question
I want to solve the question 9. Thermodynamics
Q8
An ideal air-standard Otto cycle has a compression ratio of 8. At the
beginning of the compression process, air is at 100 kPa and 300 K, and
800 kJ/kg of heat is transferred to air during the constant-volume heat-
addition process from a source at 1900 K and waste heat is rejected to the
surroundings at 300 K.
Determine
(a) the maximum temperature and pressure that occur during the cycle,
(b) the specific net work and the thermal efficiency,
(c) the mean effective pressure for the cycle,
(d) the exergy destruction associated with each of the four processes and
the cycle and
(e) the second-law efficiency of this cycle.
Q9
If the ideal air-standard Otto cycle operates between the lowest
temperature T1=300 K, and T3=1803.42 K, and at the compression ratio
of optimal instead of 8, repeat Q8
