- $$ \dot{m}_{in} - \dot{m}_{out} = \frac{dm_{CV}}{dt}$$
Hello All,
I have a problem to understand this equation:
$$ \dot{m}_{in} - \dot{m}_{out} = \frac{dm_{CV}}{dt} $$
It supposed to describe change in the mass of the control volume during a process.
Two terms on the left are the total mass flow rates in and out of the system. I struggle to understand RHS.
What $$ \frac{dm_{CV}}{dt} $$ means and why it is not equal to $$\dot{dm_{CV}}$$?
Many thanks for all your help.
