What else can I help you with?
What is the maximum work obtainable from two bodies at temperatures T1 and T2 . i need derivation. pls help you out?
To obtain the maximum work/time (power) from two bodies at different temperatures, you have to put an "Ideal" Heat Engine between the two bodies. The Heat Engine works with the "Carnot Thermodynamic Cycle". The Heat Efficiency of the Carnot Cycle Engine is called "Carnot Efficiency" and it only depends on the Absolute Temperature of the two bodies. Absolute Temperature also known as Thermodynamic Temperature will be in Rankine degrees, oR, (U.S.C.S.), or Kelvins (I.S.). The Carnot Heat efficiency is given by; eff (%) = [1 - TL/TH] x 100 where TH and TL are the High and Low Thermodynamic Temperatures of the bodies. So if a given Carnot Efficiency turns out be of 35%, this means that from the heat given by the High Temperature body, 35% is converted to work and the rest is dumped to the Low Temperature body.
What is the carnot statement of the second law of thermodynamics?
The efficiency of a quasi-static or reversible Carnot cycle depends only on the temperatures of the two heat reservoirs, and is the same, whatever the working substance. A Carnot engine operated in this way is the most efficient possible heat engine using those two temperatures
What is the efficiency of a carnot engine operating between boiling point and freezing point of water?
You must insert the temperatures, in Kelvin, into the formula. Freezing point of water: 273 K; boiling point of water: 373 K. Thus, you get a Carnot efficiency of (373 - 273) / 373, or about 27%.
Can you have maximum gravitational potential energy and maximum gravitational kinetic energy at the same point?
No, gravitational portential energy is more with more hight and gravitational kinetic energy is maximum just before reaching the ground.
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 a carnot's engine?
a Carnot cycle is a perfect cycle of energy conversion from heat to mechanical energy and back without loss. This is an impossibility due to losses inherent in any energy transfer. A Carnot engine would theoretically use all available energy for each energy transfer.
What is the coal energy efficiency?
If it is burned - which is the way such fuels are usually used - the energy efficiency is the energy efficiency of a heat engine. The theoretical maximum efficiency is the Carnot efficiency; the real efficiency will usually be considerably less than that.
Which is the carnot engine formula?
carnot = carrot
What is carnots engine?
a Carnot cycle is a perfect cycle of energy conversion from heat to mechanical energy and back without loss. This is an impossibility due to losses inherent in any energy transfer. A Carnot engine would theoretically use all available energy for each energy transfer.
What is the relationship between a hurricane and the Carnot cycle?
A hurricane and the Carnot cycle are both related to the transfer of energy. A hurricane is a natural phenomenon that involves the transfer of heat energy from warm ocean waters to the atmosphere, creating strong winds and storms. The Carnot cycle is a theoretical model that describes the maximum efficiency of a heat engine, which also involves the transfer of energy. While they are not directly related, both concepts involve the movement and transformation of energy in different ways.
What is the reverse of a carnot engine?
reverse carnot engine is also called a REFRIGERATION SYSTEM.
When was carnot engine develop?
Carnot heat engine was develop in 1824 by Nicolas Leonard.

What is known as carnot heat engin?
carnot's heat heat engine is also known as ideal heat engine.because in carnot's the precess is reversible .Total heat converted into work . The efficiency is maximum for carnot's heat engine.
What is the difference between carnot heat engine and a heat engine?
difference schematic diagram between carnot heat engine and heat engine
What is the Carnot engine problem and how does it relate to the efficiency of a heat engine?
The Carnot engine problem refers to the theoretical limit on the efficiency of heat engines, as described by the Carnot cycle. This problem highlights that no real heat engine can be 100 efficient, as some energy is always lost as heat. The efficiency of a heat engine is limited by the Carnot efficiency, which depends on the temperatures of the heat source and sink. This concept helps engineers understand and improve the efficiency of real-world heat engines.
Limitations of the Carnot cycle for the operation of the steam power plant?
The Carnot cycle gives the theoretical maximum efficiency of an engine operating between two heat reservoirs. The Carnot cycle is an idealized engine cycle that is thermodynamically reversible. Real systems such as power plants are not reversible, and the entropy of a real material changes with temperature (which is not accounted for by the Carnot cycle). A steam power plant operates closer to a cycle known as the Rankine cycle.
