I need to convert from Nl/min to l/min and I have read your explanation in “Converting Nl/min to l/min“, but I don’t understand one thing.
First let me make an introduction and then I will do the question.
The question is about the way to give the flow in the compressors. I think that when you give the flow, you have to say the flow and also the pressure (correct me please if I am wrong). For example: 10 l/min at 7 bar, 10 l/min at 5 bar… If you say 10 Nl/min it means 10 l/min in normal conditions, so it means 10 l/min at 1 bar (absolute). Is it like this?
After that explanation I don’t understand when you say: “50 Nl/min at 7 bar”. Is it ok? I think you mean that you are going to convert from 50 Nl/min to l/min at 7 bar, don’t you?
I am asking that because in our factory our compressors’ flow is given at 7 bar but the air consumption of the ejectors we want to set up is given in Nl/s. We want to know if we have enough air to install them or not, so we have to do the conversion in order to be able to compare them.
Thank you very much for your page and your service!
Also, you need to consider that Nm3/h and FAD are not exactly the same. FAD flow will depend on atmospheric pressure (altitude) and ambient air temperature and humidity. I have found an excel conversion tool from Nm3/h to FAD here:
