I asked about how I can calculate the ventilation rates and number of holes and fan speed if I want make small incubator
Hello Dr. Ashraf,
I am Tarek, a free researcher at Helwan University - Mattaria. From my experince as an Air conditioning Engineer, you won't need to worry about the ventlation rates or the number of holes or fan speed, I think you need to worry about 'Mass transfer'. If the Egg Incubator needed a certain percentage of moisture or humidity ratio, then there must be a source of water in the incubator, If I am right, then that source will be a major parameter in calculating all other factors you are asking about. Please let me know what you think and don't hesitate to call me. I'll send you my number. I am a fan of your work :)
Dear Ashraf,
For me, the most critical factors related to the egg incubator venation are to control the carbon dioxide and humidity levels (you may need a good hygrometer). Additionally, there are some of the ventilation requirements that you should take in consideration such as the incubator size, the number of eggs, and stage of incubation (during the embryonic development or growth?). I would, therefore, recommend the following book and article in addition to the references mentioned above.

As well as you can also find good information on “How to Calculate Air Requirements” in the following document.

Dear respected Ashrf Abdel Galil Anwer,
Please check my article on "Development of Solar Powered Poultry Egg Incubator for South West Nigeria". It can be of help..
