Given the volumetric flow rate of liquid air under standard conditions, how can the volumetric flow rate under actual operating conditions be calculated? The liquid-air flow rate is 56,260 Nm3/h, the operating pressure is 5.433 MPa, and the temperature is -168°C. What is the actual liquid-air flow rate under these operating conditions?

Is the liquid measured in Nm3/h? Where does liquid air come from under standard conditions?

PV=NRT; N=PV/RT. The value of N under standard conditions is equal to that under actual conditions. Solve for it – the pressure here is absolute pressure, and the temperature is in Kelvin
