I have an airflow sensor that works by I2C.

This is the sensor reading signal.
I'm having trouble transforming these read bytes that are delivered by the sensor into airflow.

What would that high airflow coefficient and low airflow coefficient be?

I am leaving the documentation attached. In the document it is demonstrated how it works, but I couldn't understand it very well yet.

 

The data is being returned in 16-bit values- each having a high byte and a low byte. The 'flow-high-nobble' is actually 'flow high nybble' - a 4-bit value.

These are binary values, which translate directly to hex or decimal by simply changing the base.

Here is a very small tutorial for hexidecimal using just a byte:
