This is forced convection heat transfer modes as it involve fluid (in this case the air) in forced motion. Hot stream of air is then directed to work surface by using nozzle which comes in various size and shape. The second forced convection heat transfer modes the takes place as hot stream of air make contact with work surface which usually involve material sub-melting. Even though every matter producing radiation mode of heat transfer‚ in this case we only focus on forced convection heat transfer

Litosphere: the rigid outer part of the earth‚ consisting of the crust and upper mantle. d. Asthenosphere: the upper layer of the earth’s mantle‚ below the lithosphere‚ in which there is relatively low resistance to plastic flow and convection is thought to occur. e. Mantle: between the crust and core f. Outer Core: Earth’s outer

D type boiler design: SZS series of boiler are design by double drum‚ longitudinal type‚ full water pipe structure. It is consist of the upper and lower drum‚ convection bank and the left and right set of boxes. The total size are close-knit‚ and the external appearance is elegant and beautiful. It apply to com-bust under slightly negative pressure because the water screen of the boiler furnace is use of close-packed

Why will the Alaskan Way Viaduct collapse? The Alaskan Way Viaduct will collapse because of an earthquake.The earthquake’s cause has to do with the layers of the Earth‚ mainly the lithosphere and the asthenosphere. The result of the lab “Density Column” proved that since the layers of the Earth are stacked on top of each other‚ like the liquids in the “Density Column”‚ the layers must have different densities. Another lab that was done in class‚ “Density Cubes”‚ showed that density‚ or

would exhibit lower body temperatures than those residing on banks alongside streams due to convection of the moving water. The results of this experiment indicated a significant difference between body temperatures of the model turtles in each microhabitat. The temperatures of the samples in the stream were significantly lower than those of the samples on the bank. These results indicate that the convection from the moving stream waters provide effective means for lowering body temperature in ectotherms

An appreciation of the principles‚ advantages and limitations of the various analytical techniques developed to determine the moisture content of foods depends on an understanding of the molecular characteristics of water. The method used was with oven drying‚ which the sample is heated under specified conditions‚ and the loss of weight is used to calculate the moisture content of the sample. After the result obtained‚ the average percentage of moisture in doughnut sample was 42.721 2.043. The

Granulations doesn’t last very long‚ and it disappear really fast. Individual granulations‚ it only visible for about only minutes. Granulations on the photosphere of the Sun are caused by convection currents (thermal columns‚ Bénard cells) of plasma with in the Sun’s convective zone. Granulations are caused by convection currents because the rising part of the granules is in the center where the plasma is hotter. The outer edge of the granules is darker due to the cooler descending plasma. In addition

Styrofoam also acts as a thermal insulation. I used the tin foil because it serves as an insulator and keeps the radiant heat inside the box. Next I used insulation‚ which does what its name is‚ it keeps whatever inside of it insulated or prevents convection. I used silicone to block off the holes from the Styrofoam to make a good box for the heat to stay in. finally I used a cork on the top of my can to have the smallest hole for the heat to escape it. III. For this experiment I
