Physics thermodynamics is a very interesting course
It isn’t just interesting but wide too

In this article I talk about mass flow rate (1) and volumetric flow rate (2). I report them below.
They are important for understanding the mass continuity equation. Let's study this equation to better understand open thermodynamic systems.
If we talk about open systems, the first thing to learn is that the first law of thermodynamics for open systems establishes that the energy associated with a M.C. (control mass) can vary over time due to two different types of energy flows, i.e. of thermal power and mechanical power.
I forgot, when we talk about open systems the second law of thermodynamics for open systems is also important and establishes the following.
The entropy associated with a control mass can vary over time due to entropic flow and entropic production.
