Thermodynamics: It a branch of science which deals with changes in energy that accompany physical or chemical changes in matter.
1.Establish feasibility of the reaction
2. Extent of reaction after feasibility is establishes
3. Deduce generalizations of physical chemistry
1.Applicable to only bulk process
2. It predicts the possibility of process but not success
3. It does not defines the mechanism of process
Heat Transfer Processes: Planck’s Law
Every object emits over the entire electromagnetic spectrum.
Stefan-Boltzmann Law
Total energy emitted by a black body is directly proportional to fourth power of its temperature.
Wien's Displacement Law
The product of peak wavelength and temperature of a blackbody radiator is constant.
Material Balance: Also known as Mass balance.
Used to find the accumulation of a contaminant/ pollutant/ substance in a particular region.
Those particular region are also called as control volume.
MASS BALANCE EQUATION
Accumulation rate = Input rate – Output rate + Reaction
rate
For Steady-State conservation Systems
Input rate = Output rate
