Transcribed Image Text:**Initial Conditions:**
- **Pressure (P1):** 30 lbf/in²
- **Temperature (T1):** 540 °F
- **Volume (V1):** 4 ft³
**Final Conditions:**
- **Pressure (P2):** 20 lbf/in²
- **Volume (V2):** 4.5 ft³
**Energy Transfer:**
- **Work Done on Air (by Wheel):** 1 Btu
- **Heat Transfer to Air:** 12 Btu
Note: The process follows **Ideal Gas Behavior**.
**Objective:**
Calculate Temperature (T2) in radians.
**Diagram Description:**
The diagram depicts a closed system containing air, with a piston and a rotating wheel doing work.
- **Q = -12 Btu:** Represents the heat energy transferred to the system.
- **WpW = -1 Btu:** Indicates the work done on the system via the wheel.
- **Wpis = ? :** Denotes the unknown work done by the piston.
The initial and final conditions are labeled clearly with the pressure, volume, and temperature values for reference.
Expert Solution
