Heat is a form of energy which transfers between bodies which are kept under thermal interactions. When a temperature difference occurs between two bodies ..
The LMTD is a logarithmic average of the temperature difference between the hot and cold fluid streams at each end of the heat exchanger. The larger the value of LMTD, ..
The flow in the heat exchanger is considered under steady-state and fully insulated at the outer surface. Consider an infinitesimal part of the heat exchanging tube ..
Nusselt’s analysis of film condensation makes the following assumptions: The film of the liquid formed flows under the action of gravity. The condensate flow ..
The law of heat conduction is also known as Fourier’s law. Fourier’s law states that Fourier’s equation of heat conduction: Where, ‘Q’ ..
Many correlations in heat transfer are based on dimensionless numbers, which are used to establish similitude among cases which might seem very different. Four ..
Heat exchanger is a process equipment designed for the effective transfer of heat energy between two fluids. For the heat transfer to occur two fluids must be at different ..
The Wien’s Displacement Law states that a black body having a wavelength (λmax) carrying the maximum energy is inversely proportional to the absolute temperature ..
When deciding on which heat-transfer fluid best suits your needs, there are some crucial factors to take into account. In solar water heating systems, these fluids ..
Machines and gadgets have made our lives easy but one must understand they are subject to wear and tear and needs to be mended or replaced at some point of time. ..
A plate and frame heat exchanger (PHE) is often a preferred option because of excellent heat transfer capability. When using this type of unit, there are several ..
Equation shown in the image is the Stefan-Boltzmann law. “P” is the power radiated by the ideal radiator and ‘σ‘ is is the Stefan-Boltzmann ..
