Difference between heat and work? Heat is low-grade energy and work is a high grade of energy. heat energy and work-energy differences are calculated by the second law of thermodynamics i.e 1KJ of heat cannot be transferred completely into the 1KJ work, some loss of heat is lost but 1KJ of work can be transferred …
What Is Law Of Conservation Of Energy: Law of conservation of energy defined as the energy that cannot be created or destroyed in a specified system, It can only be changed from one form of energy into another form. Conservation of energy develops the uses of energy in the global system and obtains required energy …
Light Energy: Uses and Applications of Light Energy: Light Energy: Light energy is a type of kinetic energy, which can transfer from one place to another place in the form of electromagnetic waves. Light energy can be converted into so many forms like solar energy, heat energy, chemical energy, etc. Light energy received by the …

Bukingham-π(pi) Theorem This Bukingham-π(pi) theorem is used to determined the relation by discribing the physical phenomenon to the number of independent dimensions groups. The non dimension group is given by that a large number of physical variable are involved, in a dimensionally homogeneous containing ‘m’ fundamental dimensions. It is given by (n-m). The equation is …
Fin Effectiveness: 1. The thermal conductivity of materials for a given fin dimensions is determined by it. 2. The rate of heat transfer can be calculated from the surface with and without using fins, by using fin effectiveness relationship. 3. It is also used to determine the fin performance. Fin efficiency: 1. It is important …
Thermal conductivity of solids, gases and liquids Solids: Due to transfer of free electrons and lattice vibration heat conduction occurs. In some metals like pure type the heat conduction is more effectively due to moving of free electrons in single direction. Heat energy is transfer from high temperature to low …
