Ya know ... I've got this Motorola MPX4115 sensor sitting here (from a altimeter and telemetry project I did a couple of years ago). Perhaps I'll just cobble together a circuit with a range of 15kPa to 115kPa and check the pressure in front and behind the radiator in my little Neon ...
... then again, HEY Enzo, don't you have a mechanical engineering background? So what's the answer on the pressure, velocity, and heating effects? (I'm just a poor EE who doesn't even remember thermal dynamics or fluid flow!)
