Carnot's theorem states that the signed sum of the perpendicular distances from the circumcenter of a triangle to the three sides is equal to the sum of the circumradius and the inradius of the triangle.

Carnot theorem states that no heat engine working in a cycle between two constant temperature reservoirs can be more efficient than a reversible engine working between the same reservoirs.

[SOLVED] Understanding a proof of Carnot's theorem. I'm having trouble understand this proof of Carnot's theorem, and I would appreciate it if someone could point out where my reasoning goes wrong. The proof reads thusly: Suppose there exists a a hypothetical engine with a greater The maximum efficiency is the ratio of the temperature difference between the reservoirs and the temperature of the hot reservoir, expressed in the equation = −, where T C and T H are the absolute temperatures of the cold and hot reservoirs, respectively, and the efficiency is the ratio of the work done by the engine to the heat drawn out of the hot reservoir. Carnots teorem säger: Alla irreversibla värmemaskiner mellan två värmereservoarer har lägre verkningsgrad än en Carnotmaskin som arbetar mellan samma reservoarer.

Carnot's theorem states that the signed sum of the perpendicular distances from the circumcenter of a triangle to the three sides is equal to the sum of the circumradius and the inradius of the triangle. Carnot's famous statement about the efficiency of a heat engine could be summarized as "No engine can beat Carnot engine". The key point about it is the fact that it relies solely on reversible processes.

Carnot's theorem (inradius, circumradius), describes a property of the incircle and the circumcircle of triangle. Carnot's theorem (conics), describes a relation between triangles and conic sections. Carnot's theorem (perpendiculars), describes a property of certain perpendiculars on triangle sides. In other uses :

No heat engine can be more efficient than a reversible engine operating between the same temperature limits (the temperature of heat addition and the temperature of heat rejection) and all reversible heat engines operating between the same temperature limits have the same efficiency.

According to the Carnot's theorem, the efficiency of a reversible heat engine operating between a same given constant temperature source and a given constant temperature sink is In any $\Delta ABC,\,$ the (algebraic) sum of the distances (suitably signed) from the circumcenter$O\,$ to the sides, is $R + r,\,$ the sum of the circumradiusand the inradius. $OM_{a} + OM_{b} + OM_{c} = R + r.$ In acute triangles, the circumcenter is always located inside the triangle. EXPLAIN THE CARNOT’S THEOREM AND PROOF IT in Thermal Engineering and Power Unit We were discussing various basic concepts of thermodynamics such as thermodynamic state, path, process and cycles in our previous post. We have also discussed the concept of … Carnot's Theorem from Ptolemy's Theorem. Below I shall apply Ptolemy's theoremto derive a theorem due Lazare Carnot: In any triangle $ABC,$ the (algebraic) sum of the distances (with suitable signs) from … In Euclidean geometry, Carnot's theorem, named after Lazare Carnot (1753–1823), is as follows.

the principle that no engine operating between two given temperatures can be more efficient than a Carnot engine operating between the same temperatures. Carnot's Theorem states that in a triangle, the signed sum of perpendicular distances from the circumcenter to the sides (i.e., signed lengths of the pedal lines from) is: where r is the inradius and R is the circumradius. The sign of the distance is chosen to be negative iff the entire segment lies outside the triangle. Carnot's theorem definition is - a principle in thermodynamics: an engine working in a reversible cycle is at least as efficient as any other engine working between the same limits of temperature, the efficiency of such an engine being a function of the two limiting temperatures and not dependent on the mechanical design or the working substance of the engine.
