It is not a good efficiency engine.
It is not a good efficiency engine.
If this, ie 70%, is the total energy loss, it follows that the engine is producing 30% useful energy, so that is its thermodynamic efficiency.
The efficiency of an engine that gives off thermal energy is determined by the ratio of the useful work output to the total energy input. It can be calculated using the formula Efficiency = (Useful work output / Total energy input) x 100%. A higher efficiency indicates that the engine is converting more of the input energy into useful work.
The steam turbine will produce 400 J of output, and the steam engine 250 J. That's what the efficiency figure means.

Thermal efficiency is a measure of how efficiently a system converts heat energy into mechanical work. It is calculated by dividing the desired output (such as work) by the input energy (such as heat) and is expressed as a percentage. Higher thermal efficiency indicates that more of the input energy is being converted into useful work.
The amount of work done by a heat engine is not equal to the amount of thermal energy it absorbs. In a heat engine, only a fraction of the thermal energy absorbed is converted into work, with the remaining energy typically being expelled as waste heat. The efficiency of a heat engine is a measure of how effectively it converts thermal energy into work.
The maximum Thermal Efficiency of Petrol Engine or Gasoline Engine or Otto Cycle Engine is about 25-30%.
The formula to calculate the thermal efficiency of an Otto cycle engine is: Thermal Efficiency 1 - (1 / compression ratio)
It is used to evaluate how efficient an engine converts the heat from a fuel to mechanical energy.
Indicated thermal efficiency is a measure of the effectiveness of an engine in converting the heat energy produced during combustion into useful work. It is calculated by comparing the indicated power (the power developed in the engine's cylinders) to the energy input from the fuel. This efficiency reflects the engine's performance under ideal conditions, not accounting for losses due to friction, heat dissipation, or other factors. In essence, it provides insight into how well an engine utilizes the energy from fuel.
The thermal efficiency of an internal combustion engine using the Otto cycle is a measure of how effectively it converts heat energy from fuel into mechanical work. The Otto cycle, which consists of four processes (intake, compression, power, and exhaust), plays a key role in determining the engine's thermal efficiency. By optimizing the compression ratio and combustion process within the Otto cycle, engineers can improve the engine's thermal efficiency, resulting in better fuel economy and performance.
