Density is the ratio of mass to volume. Low density objects have a low mass per unit volume because they contain fewer particles.Calculating Density You can't directly measure density, and the units of density depend on the units used for mass and volume. Usually, those are g/cm3. To cal...
and thus for the heat exchange heat exchanger, such as coke oven preheated air below the regenerator. These heat exchangers are mainly used to recover and utilize heat from high temperature exhaust. The same kind of equipment, which is used for the...
The opposite applies when water is cooled. Note: The relation among temperature, volume and density is not a linear function and it depends on the specific heat capacity, heat of vaporization and other factors of each substance. b) Air Bubbles or Impurities A simple air bubble present...
Heat is concentrated in the very small size of the chip, the chip temperature rises, causing non-uniform distribution of thermal stress, chip luminous efficiency and fluorescent powder excitation efficiency decline; when the temperature exceeds a certain value, the device failure rate is an exponentia...
Fin density Fin spacing Width Length Heat sinks are used to cool various electronics components whose heat dissipation abilities are is insufficient to dissipate all the excess heat. These devices include: Power transistors, thyristors and other switching devices ...

The size of a heat affected zone is influenced by the level of thermal diffusivity, which is dependent on the thermal conductivity, density and specific heat of a substance as well as the amount of heat going in to the material. Those materials with a high level of thermal diffusivity are ...
Pixel densityis an attribute of a display device measured as number of device pixels within one inch of screen space, either in horizontal or vertical direction. Value of pixel density is expressed as dpi(dots per inch) or ppi(pixels per inch). Historically term dpi has been used for printe...
Natural convection– where the movement of the fluid particles is caused by the local changes in density due to transfer of heat from the surface of a solid to the fluid particles in close proximity. Forced convection– where the movement of the fluid particles is caused by an additional devic...
What is the heat capacity of a gold ring that has a mass of7.00g? Specific heat: The specific heat of a substance is the amount of heat required to raise the temperature of the unit mass of the substance through a unit charge degree(1∘or1K). ...
