Heat Engine Efficiency app for iPhone and iPad

The efficiency of a heat engine relates how much useful work is output for a given amount of heat energy input. In other words, a heat engine absorbs heat energy from the high temperature heat source, converting part of it to useful work and delivering the rest to the cold temperature heat sink. Now this app provides you the solution to calculate efficiency of heat engine.This app is very interesting tool to solve for your Heat Engine Efficiency.You can analyze your heat engine using this app.

We know from the second law of thermodynamics that a heat engine cannot be 100% efficient, since there must always be some heat transfer Qc to the environment, which is often called waste heat. How efficient, then, can a heat engine be? This question was answered at a theoretical level in 1824 by a young French engineer, Sadi Carnot (1796–1832), in his study of the then-emerging heat engine technology crucial to the Industrial Revolution. He devised a theoretical cycle, now called the Carnot cycle, which is the most efficient cyclical process possible. The second law of thermodynamics can be restated in terms of the Carnot cycle, and so what Carnot actually discovered was this fundamental law. Any heat engine employing the Carnot cycle is called a Carnot engine.

Since temperatures are given for the hot and cold reservoirs of this heat engine,Efficiency=1-Tc/Th can be used to calculate the Carnot (maximum theoretical) efficiency. Those temperatures must first be converted to kelvins.

This app helps to solve many mathematical problems and you may use this app to analyze heat engine efficiency.
