An ideal dual cycle operates with a mass of 0.25 kg. The dual cycle consists of the following internally reversible processes: 12: adiabatic compression 2→ 3a: constant-volume heat addition of 2.40E5 J/kg 3a → 3b: constant-pressure heat addition of 4.00E5 J/kg 3b→ 4: adiabatic expansion 4→ 1: constant-volume heat removal Properties of states 1 and 2 are given: State 1 2 T, K 300 810.6 P, bar 1.00 32.423 a) Find the temperature, pressure, and volume in states 3a, 3b, and 4 b) Find the work done by the gas during processes 2-3a, 3a-3b, and 3b-4.
