Transport Processes (SKKK 2313) ASSIGNMENT # 1 1. Consider a steam pipe of length L=20 m‚ inner radius r1=6 cm‚ outside radius r2=8 cm‚ and thermal conductivity k=20 W/m.k. The inner and outer surfaces of the pipe are maintained at average temperatures of T1=150oC and T2=60oC‚ respectively. Obtain a general relation for the temperature distribution inside the pipe under steady conditions‚ and determine the rate of heat loss from the steam through the pipe. Assume that heat transfer is one-dimensional

large amounts of heat or cold in a definite volume is the subject of research for a long time. Thermal storage plays an important role in building energy conservation‚ which is greatly assisted by the incorporation of latent heat storage in building products. Devices which store heat during peak power operation and release the same during reduced power operation. Phase change material is one of the thermal

evaporative cooler is constructed using direct evaporative cooling method and solid desiccant dehumidification method. The model was installed in the testing environment. The results show that the evaporative cooler is provided the sufficient level of thermal comfort to the people changing relative humidity slightly. 1. Introduction This paper based on the research and development project conducted by the undergraduates as requirement of fulfilling the degree to develop a cooler unit to suit industrial

I used the Styrofoam as a box to put the can in and the 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

html >http://www.youtube.com/watch?v=empEMs-2zmA Edit Autoclaved aerated concrete is a versatile lightweight construction material and usually used as blocks. Compared with normal (ie: “dense” concrete) aircrete has a low density and excellent insulation properties. The low density is achieved by the formation of air voids to produce a cellular structure. These voids are typically 1mm – 5mm across and give the material its characteristic appearance. Blocks typically have strengths ranging from

evaporates‚ the vapour will be less dense than the liquid. Because the fluid is less dense than the bulk fluid‚ it will rise and cool fluid will replace it. Natural convection currents are set up. Clearly the rate of heat transfer depends on the thermal conductivity of the fluid in contact with the surface and the volumetric expansion properties of the fluid. The flow of fluids over a surface is also a major topic in fluid mechanics and the work on boundary layers covered in other
