Good example of the features of the python library. Your example python is so short, everything gets done auto-magically inside the "task".

Having done gas flow calculations in my youth, (but in pipes, not open air, so there's that), I want to mention that laminar flow is parabolic. As you state, your flow is likely turbulent, so it will have a rounded-rectangle shape, and it will have a lot of temperature mixing going on.

I grabbed that picture from

https://engineeringlibrary.org/reference/laminar-and-turbulent-fluid-flow-doe-handbook

Also, in the open air, hot air rises, so I'd expect your maximum temperature would move higher as you got further away from the heater. Doing it by hand must be rather difficult to do in 90 seconds.

You might want to include a humidity sensor for your testing.

The more water in the air increases the heat delivery capability for the same volume of air being moved.

Nice to see the manufacturer providing Python libraries, that's really awesome. It also opens up their product to all sorts of users.
It's on my list of 'things to learn', to (a) learn how to create libraries for Python using C (currently I resort to building C executables and then using os.system()) and (b) learn Django or similar - currently I use Node.js because that's the simplest route to web server that I know.

There was some news article recently (can't find the link) that Python performance will be improved significantly in an upcoming release, and it could also be as commonplace one day to use Python for web as it is to use JavaScript.
