For a Carnot engine to achieve 100 percent efficiency, the temperature of the cold reservoir would need to be absolute zero (0 Kelvin). This is because the efficiency of a Carnot engine is given by 1 - (Tc/Th), where Tc is the temperature of the cold reservoir and Th is the temperature of the hot reservoir, and efficiency is maximized as Tc approaches absolute zero.

What temperature is required to transfer waste heat to the environment for an heat engine to be 100 percent efficient?

For a heat engine to be 100% efficient, it would require the hot reservoir (where heat is input) to be at a higher temperature than the environment to allow for heat transfer. However, it's not possible to achieve 100% efficiency due to the second law of thermodynamics, which states that some amount of energy will always be lost as waste heat during the conversion process.


Why is is that is impossible to have a 100 percent efficiency?

It is impossible to achieve 100 percent efficiency due to various factors such as friction, heat loss, and energy conversion losses. These factors result in some amount of energy being wasted in any process, making perfect efficiency unattainable.


Why isn't it possible to attain an efficiency of 100 percent in heat engines?

It is impossible to achieve 100% efficiency in heat engines due to the second law of thermodynamics, specifically the Kelvin-Planck statement, which states that it is impossible for any device that operates on a cycle to receive heat from a single reservoir and produce an equivalent amount of work. Some amount of energy will always be lost as heat to the surroundings, limiting the maximum efficiency that can be achieved.


What temperature is required to transfer waste heat to the environment for a heat engine to be a 100 percent efficient?

In order for a heat engine to be 100 percent efficient, the temperature of the cold reservoir where waste heat is transferred should be absolute zero (0 Kelvin). This is not achievable in practice, as it violates the second law of thermodynamics.


What temperature is required to transfer waste heat to the environment for a heat engine to be 100 percent efficient?

A heat engine can never be 100% efficient due to the second law of thermodynamics, which states that some heat energy will always be lost to the surroundings. The temperature required for maximum efficiency is the temperature of the heat source for the engine. The efficiency of a heat engine is determined by the temperature difference between the heat source and the environment.

Is it possible to attain an efficiency of 100 percent in heat engines?

The maximum efficiency of the carnot engine only depends on two factors: 1 - The temperature of the hot reservoir (TH) 2 - The temperature of the cold reservoir (TC) And is given by (TH - TC) / TH « or » 1 - TC / TH So by that we can see the maximum efficiency (100%) would be when the difference of temperatures between the two reservoirs is infinite.


What is the efficiency of most power plants?

Light water nuclear plants like PWR and BWR have efficiency of about 33 percent, that is the ratio of electric output to reactor thermal output. Gas cooled reactors can be up to 40 percent as they work at higher temperature.


Can you achieve 100 percent efficency with a lever and fulcrum?

Not if you consider the energy expended to grip or engage the lever--this does account for a minimum amount of lost efficiency
