Respuesta :
The efficiency of the engine is 0.138 %.
Steps
Qh = 97.4 kj
Exhausts energy as heat = Ql = 84.0 kj
The values of efficiency ε ;
ε = 1 - [Ql- Qh]
ε = 1 - 0.862
ε = 0.138 %
Therefore, the efficiency of the engine is 0.138%.
What is an engine's efficiency?
The ratio of useful work completed to heat produced is used to determine an engine's efficiency. is the task finished.
This implies that the work produced by thermodynamic expansion is reduced by the friction and other losses.
The importance of efficiency in heat engines
How much usable work is produced for a given amount of heat energy input is related to the efficiency of a heat engine.
In other words, a heat engine takes heat energy from a high-temperature heat source, converts some of it into usable work, and releases the remaining energy as waste heat into a low-temperature heat sink.
