Is there any test to determine the cardiovascular risk of patients with obesity? from the perspective of obesity?

We found tests to determine cardiovascular risk taking into account lipid profile, blood pressure, age, history of diabetes, other laboratories. But when weight is involved, there is a paradox. I...

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...

Calculation of gas mass flow typically depends on the (experimental) discharge coefficient of the nozzle, which relates to its orifice diameter and internal diameter of upstream pipe. It also depends on the magnitude of the Reynolds number at the nozzle orifice, and on further characteristics of the actual nozzle ― possibly specified according to some applicable standard. Calculation details are presented at some engineering textbooks/handbooks that deal with gas dynamics (e.g.):
