Gas concentration in food container

I need to do some calculations of O2, CO2, and Ethylene concentrations in a food container with a fixed volume and one or several orifices and different fruits inside (food packing for supermarkets). The calculation is focused on finding an appropriate hole size to mantain minimum 02 and Ethylene levels within the container for a pair of fruits inside of the container. The output should be an Excel spredsheet that I can modify parameters for:

Container volume

Fruit mass

Fruit respiration rate

Fruit ethylene production rate

At least 2 different fruit types inside the container

As part of the job , the person should be able to advice me on basic questions on gas difussion rates inside the container (translated to tangible diffussion speeds and times to get a uniform atmophere inside the container, if possible), to place the hole or holes on the container.
