In general the calculation is done in terms of outlet : (% O 2 outlet % O 2 inlet) % of false air = * 100 % (20,95 % O 2 % inlet) Whereas 20,95 % O 2 is said to be the average concentration of oxygen in dry air. But the calculation can also be done as a calculation of the total volume of false air: (20,95 % O 2 % outlet) V2 = Vt *
