Can someone illuminate me about this equation? I am trying to understand how the 4525 can be used to calculate airspeed. Bernoulli’s equation maybe? Thank you.

The highlighted bit is just conversion from psi to pascals, the rest that you’ve show is just getting the differential pressure from the sensor. To convert to airspeed, it may be calculated somewhere else in the code to be equal to the root of twice the differential pressure over the air density.
