efficiency n=1 -(q1/q2) for a normal heat engine
But how efficiency n=1 -(t1/t2) ? for reversible heat engine
But how efficiency n=1 -(t1/t2) ? for reversible heat engine
A heat engine is a device that converts heat energy into mechanical work through a thermodynamic cycle.
A heat engine works by taking in heat from a high temperature source, such as burning fuel, and converting some of that heat into mechanical work. The remaining heat is released to a lower temperature sink. This process is repeated in a continuous cycle.
The efficiency of a heat engine is the ratio of the work output to the heat input. In other words, it is the percentage of heat energy that is converted into mechanical work.
The efficiency of a heat engine is affected by several factors, including the temperature difference between the heat source and sink, the type of working fluid used, and the design and construction of the engine.
No, the efficiency of a heat engine cannot be 100% due to the second law of thermodynamics, which states that it is impossible to convert all heat energy into work. Some heat must always be released to the lower temperature sink.
