Orifice Plate and Fluid dynamics!

It’s a device which allows you to compute the mass flow within a pipe. The implementation with arduino is very easy.

WHAT DO YOU NEED TO KNOW?
Physics, Fluid dynamics (Reynold’s number, Bernoulli equation), Numerical Analysis.

WHAT DO YOU NEED?
An Orifice Plate (there are different types of it, the model “D and D/2 tappings” is the easiest to build, so I recommend it to you, but if you want to learn more about the other prototypes, check the UNI ISO 5167-1-2 2003)
Arduino UNO
MPX 5050dp
thermocouple MAX 6675
HOW DOES IT WORK?
An orifice plate is a device which allows the user to calculate the axial velocity (and so the mass flow) of a fluid, within a pipe. For example, it is used in power stations, labs or airplanes (Pitot Tubes)!

In this case, I’ve built the model: “D and D/2 tappings”.

One of the most important physics law involved in this process is the “Bernoulli’s law”.”
