SUMMARY
The discussion focuses on calculating the airflow required from a machine to supply an engine needing 1 m3/min at standard conditions (p=101.325 kPa, T=293.15 K) while the machine operates at a pressure of 700 kPa. Using the ideal gas law, the user calculated the number of moles (n) as 0.04157 and subsequently determined the required volume flow rate from the machine to be 0.14475 m3/min. The calculations are based on the equations pV=nRT and V2=(nRT)/p, confirming the relationship between pressure, volume, and temperature in gas flow.
