What is Kelvin Planck and Clausius statement of thermodynamics?

In other words, heat engines must exchange heat with two thermal reservoirs, including a heat source and a heat sink. The Kelvin-Planck statement is the statement of the second law of thermodynamics for heat engines, while the Clausius statement is the statement of the refrigerators and heat pumps.

What is meant by Kelvin-Planck statement?

The Kelvin–Planck statement (or the Heat Engine Statement) of the second law of thermodynamics states that it is impossible to devise a cyclically operating heat engine, the effect of which is to absorb energy in the form of heat from a single thermal reservoir and to deliver an equivalent amount of work.

What is Kelvin Planck and Clausius statement how will you prove their equivalence?

The Clausius and Kelvin-Planck statements of the second law are entirely equivalent. This equivalence can be demonstrated by showing that the violation of either statement can result in violation of the other one. If such an arrangement is possible it would also violate Kelvin-Planck statement.

Which machine works on the principle of Kelvin statement?

Working of Heat Engine: For the operation of the heat engine, the working fluid has to continuously exchange heat between heat sink/reservoir with low temperature QL and heat source/reservoir with high temperature QH . The prime parameter involved here is efficiency.

What is the Kelvin Planck expression of the Second Law of Thermodynamics?

Kelvin-Planck Statement of the Second Law: “It is impossible to construct a device which operates on a cycle and produces no other effect than the production of work and the transfer of heat from a single body”.

What is available and unavailable energy?

The Carnot cycle and the available energy is shown in figure. The area 1-2-3-4 represents the available energy. The shaded area 4-3-B-A represents the energy, which is discarded to the ambient atmosphere, and this quantity of energy cannot be converted into work and is called Unavailable energy.

What is difference between heat pump and refrigerator?

A refrigeration system cools the external fluid flowing through the evaporator, whereas a heat pump heats the external fluid flowing through the condenser. The main difference between a refrigerator and a heat pump is in the manner of operation regarding cooling or heating.

What is the Kelvin Planck expression of the second law of thermodynamics?

What is the relation between COP of heat pump and refrigerator?

Explanation: (Heat leakage from a heat pump to surroundings)=(COP of refrigerator + 1)*(work done on pump).

What is the difference between COP and efficiency?

Efficiency relates to the use of all inputs in producing any given output, including personal time and energy. The coefficient of performance or COP (sometimes CP) of a heat pump is the ratio of the heating or cooling provided over the electrical energy consumed.

What is PMM1 and PMM2?

Perpetual Motion Machine (PMM) of the First Kind (PMM1) would be one to violate the 1st Law of Thermodynamics, to permanently produce useful energy (work) without any energy source, or to produce more ‘energy’ than consumed (thus generate energy from nowhere); and Perpetual Motion Machine of the Second Kind (PMM2) …

What are the two statements of Second Law of Thermodynamics?

We now present two statements of the Second Law of Thermodynamics, the first regarding a heat engine, and the second regarding a heat pump.

What is the Kelvin-Planck statement and why is it important?

The Kelvin-Planck Statement: It is impossible to construct a device which operates on a cycle and produces no other effect than the transfer of heat from a single body in order to produce work. We prefer a less formal description of this statement in terms of a boat extracting heat from the ocean in order to produce its required propulsion work:

Are Kelvin plank and second law of thermodynamics equivalent with each other?

But if we will analyze these statements, we will conclude that both statements i.e. Kelvin plank statement and Clausius statement of second law of thermodynamics are equivalent with each other in each respect.

What does the second law of thermodynamics mean in engineering?

“It is impossible to construct a device which operates on a cycle and produces no other effect than the production of work and the transfer of heat from a single body”. Thermal Engineering The second law of thermodynamics may be expressed in many specific ways.

What are some real-life applications of thermodynamics?

The real-life applications of thermodynamics are plenty. To move the boat, heat energy is converted into work energy. The water body comprises an enormous amount of heat. So ideally we can extract heat from the water body and convert that heat completely into propulsion to work.
