What is the difference between 1st and 2nd law efficiency

Answered By: Leonars Morris Date: created: Jul 14 2021

By contrast, first law efficiency relates only to the technology actually employed, whereas second law efficiency refers to both the technology actually employed and the technology that would, at least theoretically, be the best.

Does a heat engine that has a thermal efficiency of 100% violate the first law of thermodynamics

Answered By: Lewis Patterson Date: created: Dec 26 2021

CONCEPT: The First Law of Thermodynamics states that energy is conserved throughout thermodynamic processes.

Asked By: Gregory Bennett Date: created: Aug 09 2021

What do you mean by second law efficiency What is its importance

Answered By: Lawrence Robinson Date: created: Aug 10 2021

The ratio of the increase in available work attained by the process products to the maximum useful work of the fuel consumed can be used to measure the thermodynamic efficiency (or second law efficiency) of energy use for a process.

On what does the efficiency of an ideal Carnot engine depends

Answered By: Jayden Cooper Date: created: Sep 04 2021

The temperature of the source and sink must be considered.

Asked By: Gerld Lee Date: created: Nov 18 2021

Which explains why an engine cant be 100% efficient

Answered By: Dennis Anderson Date: created: Nov 18 2021

Since heat engines cannot convert all of the heat energy into mechanical energy, their efficiency can never be 100%. A heat engine is only considered to be 100% efficient if all of the heat is converted into useful work or mechanical energy.

Asked By: Devin Howard Date: created: Jun 22 2021

Which law of thermodynamics says that efficiency of a heat engine Cannot be one

Answered By: Bernard Morris Date: created: Jun 24 2021

Which law of thermodynamics states that the efficiency of a heat engine cannot be one? Explanation: The second law of thermodynamics states that entropy change in an irreversible process has to be positive, which fundamentally forbids many processes that may be consistent with the law of conservation of energy.

Asked By: Carter Richardson Date: created: Dec 07 2021

Can the Second Law of Thermodynamics be violated

Answered By: Francis Sanchez Date: created: Dec 10 2021

The second law of thermodynamics, which states that some energy will always be lost when converting from one type to another, has been proven to be false for the first time by researchers, on the scale of thousands of atoms and molecules.23 July 2002

Asked By: Alexander Gonzalez Date: created: May 15 2021

How does the first law of thermodynamics apply to heat engines

Answered By: Caleb Hernandez Date: created: May 17 2021

The work done for each complete cycle is simply the difference between the heat Q 1 absorbed by the engine at a high temperature and the heat Q 2 exhausted at a lower temperature, according to the first law of thermodynamics, which states that W = Q 1 Q 2.

Asked By: Jordan Sanders Date: created: Aug 20 2021

What is the Clausius statement of the Second Law of Thermodynamics

Answered By: Bruce Hayes Date: created: Aug 20 2021

The Kelvin-Planck Statement reads, “It is impossible to construct a device that operates in a cycle and produces no other effect than the production of 24 September 2019,” while the Clausius Statement states, “Heat can never pass from a colder to a warmer body without some other change, connected therewith, occurring at the same time.”

Asked By: Benjamin King Date: created: Oct 19 2021

How does the law of conservation of energy compare to the first law of thermodynamics

Answered By: Jesse Parker Date: created: Oct 21 2021

Energy cannot be created or destroyed; the total amount of energy in the universe is fixed; energy can be transformed into other forms or transferred from one place to another, but the total amount of energy must not change. This is the first law of thermodynamics, also known as the law of conservation of energy.

Asked By: Adrian King Date: created: Jul 15 2021

Which law of thermodynamics says that 100% efficiency is not possible

Answered By: Cyrus Long Date: created: Jul 18 2021

My understanding of the laws of thermodynamics thus far in my thermodynamics lecture course is that the first law is about the conservation of energy, the second law states that entropy must always increase or remain constant, and the third law says that heat engines can never achieve 100% efficiency, unless at T=0.

Asked By: Carlos Rogers Date: created: Apr 29 2021

What is the significance of second law of thermodynamics

Answered By: Gavin Lee Date: created: May 02 2021

The significance of this law is that it instructs us to reject as impossible any proposed process that would contravene this condition without even further investigation.

Asked By: Oswald Morgan Date: created: May 04 2021

Which statement of the Second Law of Thermodynamics states that no heat engine can have a thermal efficiency of 100 percent

Answered By: Gabriel Bell Date: created: May 07 2021

In other words, no heat engine can have a thermal efficiency of 100%, according to the Second Law of the Kelvin-Planck Statement.

Asked By: Zachary Anderson Date: created: Apr 02 2022

What is conserved in the first law of thermodynamics

Answered By: Benjamin Brooks Date: created: Apr 05 2022

The law of conservation of energy, which states that energy cannot be created or destroyed but can only be changed from one form to another, is the foundation of the first law of thermodynamics.

Asked By: Jose Edwards Date: created: May 10 2022

Why turbine is a thermodynamic heat engine

Answered By: Jaden Alexander Date: created: May 13 2022

In general, a steam turbine is a rotary heat engine that transforms thermal energy contained in the steam to mechanical energy or electrical energy. These factors help to increase the cycles efficiency.

Asked By: Jacob Robinson Date: created: Aug 08 2022

Is a boiler a heat engine

Answered By: Cole Russell Date: created: Aug 11 2022

All external combustion engines are external heat engines, but some EHEs, like solar thermal power plants, nuclear power plants, and geothermal power plants, are not external combustion engines. A boiling water reactor is an EHE.

Asked By: Ashton Stewart Date: created: Oct 25 2021

Which of the following is the Kelvin Planck statement

Answered By: Benjamin Sanchez Date: created: Oct 25 2021

It is impossible for any device that runs in a cycle to receive heat from a single reservoir and produce a net amount of work, according to the Kelvin-Planck principle.

Asked By: Xavier Jones Date: created: Dec 29 2021

What is the function of a heat engine

Answered By: Ralph Foster Date: created: Dec 30 2021

A steam engine on an antique train can generate the work required to drive the train using a heat engine, which is a device used to extract heat from a source and then convert it into mechanical work.
