  2. Kalina cycle - Wikipedia

    en.wikipedia.org/wiki/Kalina_cycle

    The same applies on the exhaust (condensing) end. This provides efficiency comparable to a Combined cycle, with less complexity. [1] By appropriate choice of the ratio between the components of the solution, the boiling point of the working solution can be adjusted to suit the heat input temperature.

  3. Thermodynamic cycle - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_cycle

    During a closed cycle, the system returns to its original thermodynamic state of temperature and pressure. Process quantities (or path quantities), such as heat and work are process dependent. For a cycle for which the system returns to its initial state the first law of thermodynamics applies: = =

  4. Heating, ventilation, and air conditioning - Wikipedia

    en.wikipedia.org/wiki/Heating,_ventilation,_and...

    Without proper ventilation, carbon monoxide can be lethal at concentrations of 1000 ppm (0.1%). However, at several hundred ppm, carbon monoxide exposure induces headaches, fatigue, nausea, and vomiting. Carbon monoxide binds with hemoglobin in the blood, forming carboxyhemoglobin, reducing the blood's ability to transport oxygen.

  5. Organic Rankine cycle - Wikipedia

    en.wikipedia.org/wiki/Organic_Rankine_cycle

    T-s diagram for the ideal/real ORC. The working principle of the organic Rankine cycle is the same as that of the Rankine cycle: the working fluid is pumped to a boiler where it is evaporated, passed through an expansion device (turbine, [3] screw, [4] scroll, [5] or other expander), and then through a condenser heat exchanger where it is finally re-condensed.

  6. Carnot cycle - Wikipedia

    en.wikipedia.org/wiki/Carnot_cycle

    A Carnot cycle is an ideal thermodynamic cycle proposed by French physicist Sadi Carnot in 1824 and expanded upon by others in the 1830s and 1840s. By Carnot's theorem, it provides an upper limit on the efficiency of any classical thermodynamic engine during the conversion of heat into work, or conversely, the efficiency of a refrigeration system in creating a temperature difference through ...

  7. Devanagari transliteration - Wikipedia

    en.wikipedia.org/wiki/Devanagari_transliteration

    WX notation is a transliteration scheme for representing Indian languages in ASCII. This scheme originated at IIT Kanpur for computational processing of Indian languages, and is widely used among the natural language processing (NLP) community in India. The notation (though unidentified) is used, for example, in a textbook on NLP from IIT ...

  8. Project management - Wikipedia

    en.wikipedia.org/wiki/Project_management

    Project management is the process of supervising the work of a team to achieve all project goals within the given constraints. [1] This information is usually described in project documentation, created at the beginning of the development process. The primary constraints are scope, time and budget. [2]

  9. Refrigeration - Wikipedia

    en.wikipedia.org/wiki/Refrigeration

    Refrigeration refers to the process by which energy, in the form of heat, is removed from a low-temperature medium and transferred to a high-temperature medium. [3] [4] This work of energy transfer is traditionally driven by mechanical means (whether ice or electromechanical machines), but it can also be driven by heat, magnetism, electricity ...
