An ideal Otto cycle has a compression ratio of 9. At the beginning of compression, air is at 100 kPa, 27oC. The pressure is doubled during the constant-volume heat addition process. Determine (a) the thermal efficiency, (b) the net work output, and (c) the MEP.  Assume variable c_p.

What-If Scenario: How do the answers change if the compression ratio is increased to 10? 

Solution: Step-by-step instructions as well as the TEST-Code can be found in the Tutorial>Daemons>ClosedCycles>Practice page. An image of the Process Panel is reproduced from the Slide Show below.
