Films using a co2 camera examining molecular attraction

Each delivery method is suspended from a test rig which is open on the front and sides. The CO2 delivery device is held 10 cm from the back plate. The backplate is 20cm wide and 40cm high. The films were recorded in a surgical environment. 

The CO2 Gas appears to act more like a liquid than a gas and this has relevance when one looks at other pages showing how a stable CO2 atmosphere is created.

As you can see there many elements that influence how CO2 will flow and the coverage it will give in various conditions.

The design of the delivery elements are important factors in how one can attain a stable CO2 atmosphere. 

If the pore size is too large then no diffusion takes place

As CO2 exits an open ended tube it does so in the same way that water would exit a tap which does not have a diffusing device in it.

It is 40cm from the top of the apparatus holding the tube. Even at the bottom of the apparatus the CO2 has only spread by 10cm (the back plate is 20cm wide). The Gas also has a strong driving force which will also be shown with the films of CO2 being delivered in a horizontal position.
