#### Problem Description:
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 shows a compressor.
- Air enters the compressor at:
- 120 kPa
- 20°C
- 10.4 L/s (volumetric flow rate)
- Air exits the compressor at:
- 1 MPa (1000 kPa)
- 300°C
#### Task:
Determine the work required by the compressor. *(You must provide an answer before moving on to the next part.)*
#### Solution:
The work required by the compressor is \( -4.578 \, \text{kJ/kg} \).
