Inwendige energie
Inwendige energie, een begrip uit de thermodynamica, is een vorm van energie die verbonden is aan het bestaan van een systeem. Het is de som van alle vormen van energie die in het systeem aanwezig zijn, zoals de bindingsenergie en bewegingsenergie van de moleculen.Afgezien van een aantal ideale systemen is de totale interne energie van een systeem moeilijk te bepalen.

Hoofdstuk 3: energie en warmte
Energie en warmte §3.1 warmte en temperatuur; het molecuulmodel. Warmte is de hoeveelheid energie die verplaatst wordt van voorwerpen met een hoge temperatuur naar voorwerpen met een lage temperatuur. Alle voorwerpen zijn gemaakt van een stof (materie), die weer is opgebouwd uit kleine deeltjes (moleculen).
Application of First Law of Thermodynamics to Flow Processes ...
In the previous chapter, we studied the first law of thermodynamics and its application to non-flow process (closed system). In this chapter, we will derive the steady flow energy equation by application of the first law of thermodynamics to flow process. The derived steady flow energy equation is then applied for analysis of engineering systems.
Chapter 4: The First Law of Thermodynamics for Control Volumes ...
The Complete Energy Equation for a Control Volume. Consider the control volume shown in the following figure. Under steady flow conditions there is no mass or energy accumulation in the control volume thus the mass flow rate applies both to the inlet and outlet ports. Furthermore with a constant mass flow rate, it is more convenient to develop the energy equation in terms of …

Steady State Flow Processes
Steady state flow processes have already been discussed in the introduction of the first law of thermodynamics for open systems, see Sect. 11.3 gure 21.1 shows an example for a simple open system with a single inlet and a single outlet. It is characteristic of open systems in a steady state that the mass in the system remains constant in time, so that the mass flux …
Steady Flow
An open system is described as a steady flow (i.e., steady state steady flow) system if the mass inside the controlled volume of the open system does not change with time. Let us consider a CV involving a steady-flow process. Mass is entering and leaving the system and there is heat and work interactions with the surroundings (Fig. 6).During a steady flow process, the total mass …
