Video of Otto Cycle Example Problem in Thermodynamics course by The Thermo Sage channel, video No. 33 free certified online
Air in the Otto cycle begins the compression process at 100 kPa and 300 K has a compression ratio of 9, and the combustion process produces 500 kJ/kg of heat. Answer the following question about the cycle using cold-air assumptions:
a) What are the temperatures at the end of the compression process, and beginning and the end of the expansion process?
b) What is the net work produced by this cycle?
c) What is the cycle thermal efficiency?
d) How much entropy is produced during the compression process? And expansion process?
