An engineer decided to design a hybrid engine half-way between the Carnot and Otto Cycles based on using 35 moles of a diatomic gas. It features (a) an adiabatic expansion for power, (b) an isothermal compression to reset, and (c) an isovolumetric temperature injection. Some of the key state values are given on the P-V chart for the transition points between the processes.
What is the
1) net work performed by the engine,
2) the amount of heat injected the isovolumetric temperature increase (QH), and
3) based on these values, what is the efficiency of the engine?
Solve for other state variables as necessary
How much more efficient would a Carnot engine be acting between these same temperatures?
