NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. An adiabatic air compressor compresses 10.4 L/s of air at 120 kPa and 20°C to 1000 kPa and 300°C. The constant pressure specific heat of air at the average temperature of 160°C = 433 K is cp=1.018 kJ/kg-K. The gas constant of air is R = 0.287 kPa-m³/kg-K.

Question
### Educational Transcription: **Note:** *This is a multi-part question. Once an answer is submitted, you will be unable to return to this part.* An adiabatic air compressor compresses 10.4 L/s of air at 120 kPa and 20°C to 1000 kPa and 300°C. The constant pressure specific heat of air at the average temperature of 160°C = 433 K is \( c_p = 1.018 \, \text{kJ/kg.K} \). The gas constant of air is \( R = 0.287 \, \text{kPa} \cdot \text{m}^3/\text{kg.K} \). **Diagram Explanation:** The diagram depicts a compressor with labeled inputs and outputs: - **Input:** Air at 120 kPa and 20°C with a volumetric flow rate of \( V \, \text{L/s} \). - **Output:** Compressed air at 1 MPa and 300°C. **Question:** Determine the work required by the compressor. (You must provide an answer before moving on to the next part.) The work required by the compressor is \_\_\_\_\_ kJ/kg.
