Eksergiya

yex (yunon.) – ichidan.ergon - ish, kuch,

 the exergy of a system is the maximum useful work possible during a process that brings the system into equilibrium with a heat reservoir.

Entalpiya

enthalpo (yunon.) – isitaman – termodinamik sistemaning holat funktsiyasi; sistemaning ichki energiyasi bilan sistema bosimining hajmiga ko’paytmasi yig’indisiga teng.

Enthalpy is a measurement of energy in a thermodynamic system. It includes the internal energy, which is the energy required to create a system, and the amount of energy required to make room for it by displacing itsenvironment and establishing its volume and pressure.

Entropiya

entropia (yunon) – burilish, o’zgarish – termodinamik sistemaning holat funktsiyasi; sistema bilan tashqi muhit o’rtasidagi issiqlik almashinish jarayonining borish yo’nalishini, shuningdek, yopiq sistemada o’z-o’zidan sodir bo’ladigan jarayonlarning borish yo’nalishini xarakterlaydi.

 entropy (usual symbol S) is a measure of the number of specific realizations or microstates that may realize a thermodynamic system in a defined state specified by macroscopic variables. Most understand entropy as a measure of molecular disorder within a macroscopic system.

Ot kuchi

sistyemaga kirmagan quvvat birligi; 1980 y. 1 yanvardan foydalanish tavsiya etilmaydi. Byelgisi — o.k. I o.k. (myetrik) q 735,499 Vt, AQSh va Buyuk Britaniyada. hp b-n byelgilanadigan va 745,7 Vt ga tyeig bo’lgan O. k. qo’llaniladi (q. Vatt).



Horsepower (hp) is a unit of measurement of power (the rate at which work is done). There are many different standards and types of horsepower. The term was adopted in the late 18th century by Scottishengineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other types of piston engines, as well as turbines, electric motorsand other machinery. The definition of the unit varied between geographical regions. Most countries now use the SI unit watt for measurement of power.
