WebA T-s diagram is the type of diagram most frequently used to analyze energy transfer system cycles. This is because the work done by or on the system and the heat added to or removed from the system can be visualized on the T-s diagram. By the definition of entropy, the heat transferred to or from a system equals the area under the T-s curve of ...

WebFanno line or Fanno curve (Governing equation) Flow in a constant area duct with friction and without heat transfers is described by a curve is known as Fanno line or Fanno curve. Density ρ is a function of entropy and enthalpy. The above equation can be used to show a fanno-line in h-s diagram. Since entropy can only increase the processes ... WebThere are two property diagrams involving entropy in common usage, the temperature-entropy (T-s) and enthalpy-entropy (h-s) "Mollier" diagrams. We will find that the h-s diagram is extremely useful for evaluating adiabatic turbines and compressors, and complements the P-h diagram which we used in Chapter 4 to evaluate entire steam …
An enthalpy–entropy chart, also known as the H–S chart or Mollier diagram, plots the total heat against entropy, describing the enthalpy of a thermodynamic system. A typical chart covers a pressure range of 0.01–1000 bar, and temperatures up to 800 degrees Celsius. It shows enthalpy See more The diagram was created in 1904, when Richard Mollier plotted the total heat H against entropy S. At the 1923 Thermodynamics Conference held in Los Angeles it was decided to name, in his honor, … See more It can be used in practical applications such as malting, to represent the grain–air–moisture system.
