Understanding Reynolds Transport Theorem

In fluid mechanics, it is usually more convenient to work with control volumes, but most of its principles are derived from the time rate of change of extensive properties for systems. The relationship between the time rates of change of an extensive property for a system and for a control volume is expressed by the Reynolds transport theorem (RTT).
