Question

A new, cold-air-standard cycle operates between 3 states in a piston-cylinder device:

● 1 → 2: constant volume heat addition
● 2 → 3: isobaric expansion
● 3 → 1: compression such that pressure and volume have a linear relationship
For this cycle, ?_h = 2?_L, where ?_H is the high pressure and ?_L is the low pressure, respectively, and
?_1 = 1/3?_3
a) Draw this cycle on a P-v diagram.
b) Find the temperature ratios T_2/T_1 and T_3/T_1
