1 shows the influence of inlet air temperature, feed flow rate, and black mulberry concentration on the spray drying process yield. Increase in inlet air temperature from 120 to 140°C induced a significant increase in yield, which can be attributed to the greater efficiency of heat and mass transfer processes and decreasing the probability of hitting the inadequate drying particles to the drying chamber wall. Similar results were reported by Tonon et al. [21] and Goula and Adamopoulos [19]. But increasing inlet air temperature to 160 °C showed a negative effect especially for samples containing higher amount of black mulberry juice.
The flow of the real fluid in bundle of tube has significant difference compared to single tube. The flow in single tube is influenced by the Reynold number of the fluid as higher velocity cause the layer separation and forming wake region. However, in the flow across bundle of tube, the flow is influenced by the spacing and the pattern of the flow. Close spacing of the tube may prevent the interspace mixing of the fluid to enhance heat transfer. There are two types of pattern the tubes can be aligned: inline and staggered.
This structural distortion is usually due to changes in temperature as well as the tilt angle δ. Quartz type FePo4 sees great increase in cell parameters and cell volume of α phase and non linear rise with respect to changes in temperature. Main factors affecting thermal expansion includes angular variation which happens due to changes in symmetrically - independent intertetrahedral Fe-O-P bridging angles as well as the tilt angles. Therefore, the degree of the temperature affecting thermal expansion is comparable to extent of temperature affecting the tilt angle. The Landau- type model can be used to demonstrate the temperature dependence of this
At this stage the moisture content of the air is increased and causing an increase in the temperature of both wet and dry bulbs at A, B and D. At C the wet bulb temperature drops while it increases at a dry bulb. The pressure and temperature at 1 and 3 increases. The temperature entering the evaporator at 4 increases as well. How much power would be required to reduce air at a flow rate of 1 kg/s from 32 C at 60% humidity to 29 C at 30% humidity using the refrigerating circuit? (Assume a barometric pressure of 120 kPa.)
Hоwever, when emulsifying agents are present, they increase the interfacial tension and obstruct the coalescence of water drоplets. Everything what lowers the interfacial tension will aid in separation. 2.1.7 Viscosity. Viscоsity plays two primary roles in the stability of an emulsions. First, as oil viscosity increases, the migration of demulsifying agents to the water droplets oil-water interface is retarded.
Tack: the degree of surface stickiness of the adhesive; influences the strength of the bond between wetted surfaces 4.Surface energy: which influences wetting of different kind of surfaces. Materials Used: Hot melt glues usually consist of one base material with various additives. The composition is usually formulated to have a glass transition temperature (onset of brittleness) below the lowest service temperature and a suitably high melt temperature as well. The degree of crystallization should be as high as possible but within limits of allowed shrinkage. The melt viscosity and the crystallization rate (and corresponding open time) can be tailored for the application.
Some situations include things like porcelain, cup, and the majority materials. Air, nitrogen as well as sulfur hexafluoride would be the three most often utilized gaseous dielectrics. • Industrial coatings for instance parylene provide a dielectric hurdle between the substrate and its particular surroundings. • Mineral oil used substantially inside electrical transformers like a liquid dielectric and also to aid in cooling. Dielectric fluids with greater dielectric constants, for instance electrical grade castor oil, are often utilized in higher voltage capacitors to aid avoid corona eliminate and also boost capacitance.
Heat generation during FSW process mainly depends on tool rotational speed. The relationship between the welding speeds and the heat input during welding is complex however, in general, it can be said that increasing the rotation speed or decreasing the traverse speed will result in a hotter weld. In order to produce a successful weld it is necessary that the material surrounding the tool is hot enough to facilitate the extensive plastic flow required and minimize the forces acting on the tool. If the material is too cool then voids or other flaws may be present in the stir zone and in extreme cases the tool may break. At the other end of the scale, excessively high heat input may be detrimental to the final properties of the
The leading and trailing edges undergo more deformation and more adiabatic temperature rise (Fig. 7). Increasing the deformation rate results in a higher adiabatic temperature rise. Moreover, lower initial temperature leads to more flow stress and more adiabatic temperature rise. The temperature distribution coupled with the varying thickness of the airfoil profile results in the non-uniform cooling of the blade and consequently deviation of the airfoil.
Relative area of anode and cathode: Corrosion also depends upon the area of the anode and cathode. Smaller the anodic area more is the rate of corrosion because oxidation of anode occurs at faster rate. 2. Nature of corroding environment: i. Temperature: Corrosion depends on the temperature of the environment.
