Ch 5 - The First Law of Thermodynamics: Open Systems
In this lesson, we present a discussion of mass balances for open systems. We also consider the relationship between mass flow rate, volumetric flow rate and local fluid properties.
In this lesson, we apply the 1st Law of Thermodynamics to open systems. We also consider a new type of work interaction called flow work.
For processes that operate at steady-state, the general from of the 1st Law can be simplified and reduced from an ODE to an algebraic equation. We further simplify the 1st Law for some important devices: nozzles, diffusers, turbines, compressors, throttling devices, heat exchangers, mixing chambers, and pipe and duct flow.
In this short lesson, we learn how to apply the mass conservation principle to transient or unsteady processes.
