(a)
Interpretation:
The air-standard cycles are to be sketched on PT diagrams for the Carnot cycle and also explain why a PT diagram would not be helpful for depicting power cycles involving liquid/vapor phase changes.
Concept Introduction :
Initially a general treatment is given of paths on a PT diagram for an ideal gas with constant heat capacities undergoing reversible polytropic processes. Equation 3.35c may be written as:
Special cases {
Where P and T are constant
According to equation A,
(b)
Interpretation:
The air-standard cycles are to be sketched on PT diagrams for the Otto Cycle and also explain why a PT diagram would not be helpful for depicting power cycles involving liquid/vapor phase changes.
