starting from the microstructure of matter, based on quantum mechanics and statistical mechanics, by studying the mechanism of heat conduction of matter, a physical model of heat conduction is established, and the thermal conductivity can be obtained through complex mathematical analysis and calculations...
Specific volume may be calculated or measured for any state of matter, but it is most often used in calculations involving gases. The standard unit for specific volume is cubic meters per kilogram (m3/kg), although it may be expressed in terms of milliliters per gram (mL/g) or cubic ...
Until now, many analytical and numerical calculations have been performed on fluid-flow problems based on various kinds of nanofluids, mainly in research pertaining to the sectors of energy, electronics, and medicine. For instance, Jia et al.12 carried out the numerical analysis of a glazed photo...
At a pressure of 0.073 bar (absolute), the latent heat value is increased to 2407 kJ kg-l. Determination of specific gravity of milk by Lactometer Fig. Water removal in most cases gives an enormous reduction in volumeand weight. You can target the Engineering ToolBox by using AdWords Manag...
At the bottom of the page there are some examples of calculations using hot and cold air. See also Air Composition and molecular weight , Density at varying pressure , Diffusion Coefficients for Gases in Air , Dynamic (absolute) and kinematic viscosity , Prandtl Number , Specific heat at ...
Here polynomials of specific enthalpy and entropy are utilized, obtained by integration of the standard polynomials for specific heat. In these methods, a formula for specific heat is therefore still required. The use of specific enthalpy and entropy for performance calculations is now almost ...
See the Specific Dissipation Heat Transfer block for more detail on the heat transfer calculations. Composite Structure The block is a composite component. A Specific Dissipation Heat Exchanger Interface (G) block models the gas flow on side 1 of the heat exchanger. Another models the gas flow ...
Sensible and latent heat of moist air. Moist Air - Properties Psychrometric table with humid air properties like saturation pressure, specific volume, enthalpy and entropy. Moist Air - Relative Humidity Relative humidity in moist air is the ratio of partial vapor pressure to air pressure. Moist...
In summary, specific heat capacities of ideal gases don't depend on the molar mass of the gas, this is a clear sign you are thinking in the right direction. However, when two substances have the same temperature, the particles have the same average kinetic energy. This is why it is ...
