REFRIGERATION LAWS CLASS NOTES FOR MECHANICAL ENGINEERING Evaporator abstracts heat from the products/space to be cooled. Compressor adds energy to raise its temperature and pressure. This enabled the refrigerant to lose heat in the condenser equal to the sum of cooling effect and work input. High pressure helps the refrigerant to re-circulate. Re-circulation causes the cooling…
FICK’S LAWS CLASS NOTES FOR MECHANICAL ENGINEERING Maxwell-Stefan equations are used for the mass transfer in multi-component mixtures. Fick’s laws equations are limiting equations of Maxwell-Stefan equations. In these, it has been assumed that the mixture is extremely dilute. Further assumption is that every chemical species is interacting only with the bulk mixture and…
LAWS OF THERMODYNAMICS CLASS NOTES FOR MECHANICAL ENGINEERING Laws of thermodynamics deals with thermal equilibrium. First law deals with heat conversion into work. Complete conversion of heat into work is not possible. All process in nature are irreversible. Second law talks of irreversibility. Third law gives irreversibility is due to increase of entropy in…
