Thank you for your reply. The openings here are around peep doors and cannot just be covered but need a new concept of sealing. As this implies a serious cost, I would like to perform a benefit calculation based on the losses by air ingress.

The actual problem is small openings in a furnace that is under a slight vacuum. There are several openings of an average of 1 mm by 240 mm (appx. 100 - 150 openings). I would like to calculate the losses related to the excess oxygen that you need for complete combustion and the extra air that...

Thanks!

My name is Marc. I live in Belgium and have graduated as a chemical engineer in 1991. I have had a broad interest in anything related to engieneering and physics, but must admit that I have forgotten a lot since I graduated.

Hello, I have to calculate the air flow through a small rectangular opening with following data: - temperature at one side: 1200°C - temperature at other side: 20°C - pressure at hotter side is 3 mm WC lower than the colder side - the length of the opening is 240 mm - the width of the opening is...
