How to calculate the average nitrogen purity?
Thread Content
That’s what the newly compiled Q&A on oxygen workers says； ((Amount of nitrogen × Purity of nitrogen) + (Amount of contaminated nitrogen × Purity of contaminated nitrogen)) ÷ (Amount of nitrogen × Amount of contaminated nitrogen). I feel like it’s not written correctly. Seeking advice from experts!
It should be “nitrogen volume + contaminated nitrogen volume”; a printing error

The level of average nitrogen purity mainly depends on the purity and quantity of pure nitrogen as well as impure nitrogen: (amount of nitrogen × purity of nitrogen + amount of impure nitrogen × purity of impure nitrogen) ÷ (amount of nitrogen + amount of impure nitrogen). I’m sorry; I didn’t pay attention to the moderator’s reply, so I’ve added a sentence specifically
