Thanks for your answer. So if it is a rate of change, why is it not written as: $$ \dot{dm_{CV}} $$ My assumption is, LHS can be also written as: $$ \frac{{dm_{in}}}{dt} - \frac{{dm_{out}}}{dt} = ... $$

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...

Hello, I've got one problem with fluid flow reaction force which acts on compressor. I hope you can help me with that. Here is a sketch to my question: I wonder in which direction resultant force will be directed. I understand that air is flowing from left to right with inlet velocity V1...
