Classification of Thermodynamic Cycles 5 Sep 2011 | 03:57 pm
The thermodynamic cycles, in general, may be classified into the following two types; 1. Reversible Cycle or ideal cycle 2. Irreversible or natural or real cycle
Assumptions in Thermodynamic Cycles 27 Aug 2011 | 03:47 pm
The analysis of all thermodynamics cycles is based on the following assumptions: 1. The gas in the engine cylinder is a perfect gas, i.e. it obeys the gas laws and constant specif...
Law of Equipartition of Energy 25 Aug 2011 | 06:18 pm
This Law states, "The total energy of a molecule is shared equally by the various degrees of freedom possessed by it." In case of mono atomic molecules like ar...
Degrees of Freedom 25 Aug 2011 | 06:07 pm
In order to describe completely the motion of a particle in one plane, only two quantities must be known, say its two rectangular components. Similarly, for a particle moving ...
Assumptions in the Kinetic Theory of Gases 19 Aug 2011 | 04:57 pm
The kinetic theory of gases is based on the following assumptions: 1. The volume of a gas consists of a large number of minutes particles called molecules. it has been experimentally found that there...
Clausius Inequality 18 Aug 2011 | 04:36 pm
The Clausius inequality state that whenever a closed system undergoes a cyclic process, the cyclic integral of &Q/T is less than zero for an irreversible cyclic process and equal to zero fo...
Units of Entropy 11 Aug 2011 | 09:29 pm
The unit of entropy depends upon the unit of heat employed and the absolute temperature. We know that Change in entropy (dS) = &Q/T ...
Available and Unavailable Heat 10 Aug 2011 | 08:13 pm
The heat energy of a system is considered to have the following two parts: 1.Available heat energy 2.Unavailable heat energy The available heat energy is that part of the heat energy whi...
Importance of Entropy 9 Aug 2011 | 08:26 pm
The maximum possible efficiency obtainable by any engine working on a reversible Carnot Cycle is given by n = T1-T2/T1 where ...
Relation Between Heat and Entropy 8 Aug 2011 | 07:04 pm
Consider the heating of a working substance by a reversible process as shown whose base represents the entropy and the vertical ordinate represents the absolute temperature. Now Consider any point A ...
