What is the efficiency of an engine that gives off 70 percent thermal enery?
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.
A steam turbine has an efficiency of 40 percent A steam engine has an efficiency of 25.0 percent Suppose both devices are provided with 1000J of thermal energy How much more useful work will the ste?
The steam turbine will produce 400 J of output, and the steam engine 250 J. That's what the efficiency figure means.
What energy does the steam engine use?
steam engine uses thermal energy to convert water into steam and then uses pressure of steam to move the engine .thus thermal energy into pressure and further pressure into mechanical energy.
What is the range of thermal efficiency of good IC engine at rated load?
60 to 70%
Tell me about engine?
An engine is a motor that converts thermal energy to mechanical work.
What is efficiency of an engine that gives off 70 percent thermal energy?
It is not a good efficiency engine.

What is the efficiency of an engine that gives off thermal energy?
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.

Is it true that thermal efficiency of a diesel engine equals indicated thermal efficiency - brake thermal efficiency?
no
What is thermal efficiency?
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.
What is thermal efficiency of petrol engine?
The maximum Thermal Efficiency of Petrol Engine or Gasoline Engine or Otto Cycle Engine is about 25-30%.
What is the formula to calculate the thermal efficiency of an Otto cycle engine?
The formula to calculate the thermal efficiency of an Otto cycle engine is: Thermal Efficiency 1 - (1 / compression ratio)
The amount of work done by a heat engine equals the amount of thermal energy?
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.
What is the Significance of brake thermal efficiency?
It is used to evaluate how efficient an engine converts the heat from a fuel to mechanical energy.
What is the relationship between thermal efficiency and the Otto cycle in internal combustion engines?
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.
