Preheat Factor in a Multi-Stage Compressor
Preheat factor is defined as the ratio of the actual enthalpy rise in a stage to the isentropic enthalpy rise in that stage. In a multi-stage compressor, the preheat factor plays a crucial role in determining the overall performance of the compressor.
Explanation of the True Statement
Preheat Factor Greater than One
The true statement mentioned in option 'C' states that the preheat factor for a multi-stage compressor is greater than one. This implies that the actual enthalpy rise in each stage of the compressor is higher than the isentropic enthalpy rise.
Significance of Preheat Factor
A preheat factor greater than one indicates that the compressor is experiencing some form of inefficiency, which could be due to factors such as internal losses, leakage, or friction. This can lead to an increase in the temperature of the compressed air, affecting the overall performance of the compressor.
Impact on Performance
When the preheat factor is greater than one, it means that the compressor is not achieving the desired level of compression efficiency. This can result in higher energy consumption, reduced output, and potentially increased wear and tear on the compressor components.
Conclusion
In summary, the preheat factor for a multi-stage compressor being greater than one signifies inefficiencies within the compressor system that can impact its performance and efficiency. Monitoring and optimizing the preheat factor is essential for ensuring the effective operation of a multi-stage compressor.
