Does this below seem correct? Considerations: 1) Airflow/Delivery Pressure chracteristic 2) Speed increased/decreased Firstly, having drawn a graph of mass flow of air vs. pressure, I have noticed that there is a strong negative correlation. Hence, therefore, the greater mass flow of air passing through the compressor each second, the lower discharge pressure is acheived. Secondly, when considering the speed of the compressor, an increase in speed will increase the mass flow of air per second, which will in turn decrease the delivery pressure? Thanks!
