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 is the range of thermal efficiency of good IC engine at rated load?
60 to 70%
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.
Tell me about engine?
An engine is a motor that converts thermal energy to mechanical 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 thermal efficiency?
Thermal efficiency is the efficiency of a heat engine measured by the ratio of the work done by it to the heat supplied to it.
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.
Compare the two stroke and four stroke engine in powe output and thermal efficiency?
compare the two stroke and four stroke engine in power output and thermal efficiency?
What is the definition of thermal efficiency?
the efficiency of a heat engine measured by the ratio of the work done by it to the heat supplied to it.
What is definition of thermal efficiency of gas engine?
In general, efficiency is the ratio between the output of a device and the input, . For thermal efficiency, the input, , to the device is heat, or the heat-content of a fuel that is consumed. The desired output is mechanical work, , or heat, , or possibly both.From the first law of thermodynamics, the energy output can't exceed the input, so
How does compression ratio affect engine efficiency and performance?
Engine efficiency is increased though compression ratio by allowing a more thermodynamic energy to be converted into mechanical energy. Energy transfer is the key to efficiency.
