What is an isotherm on a P-V diagram?
Isotherm – in thermodynamics, a curve on a P-V diagram for an isothermal process. Moisture sorption isotherm – a curve giving the functional relationship between humidity and equilibrium water content of a material for a constant temperature.
What is T and S in TS diagram?
A temperature–entropy diagram, or T–s diagram, is a thermodynamic diagram used in thermodynamics to visualize changes to temperature and specific entropy during a thermodynamic process or cycle as the graph of a curve.
What are isotherms in chemistry?
An isotherm is a line drawn on a map or chart that connects points of equal temperature. That is, the temperature values are the same at any point along an isotherm.
What is H in HS diagram?
Enthalpy Entropy (h-s) or Mollier Diagram – Thermodynamics The Mollier diagram, shown in Figure A-1 , is a chart on which enthalpy (h) versus entropy (s) is plotted. It is sometimes known as the h-s diagram and has an entirely different shape from the T-s diagrams.
How do you convert a PV graph to a TS graph?
Constant volume process: Slope of constant volume line on T-s diagram = T / Cv. This knowledge will be all to convert isometric process (v=constant) from P-v into T-s diagram.
Which process is indicated by straight line on TS diagram?
Straight line on P – T graph for an ideal gas represents isochoric process.
What do isotherms mean?
isotherm, line drawn on a map or chart joining points with the same temperature. Isotherms are commonly used in meteorology to show the distribution of temperature at the Earth’s surface or on a chart indicating constant level or constant pressure.
What are the main components of the Rankine cycle?
Let’s see the diagram of the Rankine cycle and its main components. Work done incurs to the system. Pressure is increased in this stage. Point 2-3 represents the boiler in the cycle. Heat is added to the high pressured fluid by the boiler. Temperature is increased up to a boiling point. Water changed into vapor as its phase is changed.
What happens to waste heat in the Rankine cycle?
Point 3-4 indicates the turbine in the Rankine cycle diagram. Expansion of vapor happens in the turbine. Point 4-1 indicates the condenser. Waste heat is removed from the condenser with the help of the condensation process. In the ideal Rankine cycle, there are four processes running, we will check each of them and what will happen in each process.
Which is an ideal gas for a PV diagram?
An ideal gas is one that never condenses regardless of the various changes its state variables (pressure, volume, temperature) undergo. In addition, the processes plotted on PV diagrams only work for a closed system (in this case the ideal gas), so there is no exchange of matter, but still an exchange of energy.
What does the Purple Line on the pressure volume diagram mean?
The purple line represents an adiabat, while the dashed line (–) are isotherms. The various processes seen above can be combined to create cycles found in most internal and external combustion engines.
