I will rate, thank you.
3. A tungsten light bulb filament (see the figure at the right) is a coil of a coil to reduce evaporative losses (the light bulb itself contains an inert gas to also reduce evaporative losses and to also reduce the operating temperature of the filament. The inert gas is usually argon). The uncoiled diameter of the filament is 47 μm and the...
IF YOU CANNOT SOLVE THEM ALL THEN PLEASE DONT SOLVE ANY.
A hollow aluminum sphere, with an electrical heater in the center, is used in tests to determine the thermal conductivity of insulating materials. The inner and outer radii of the sphere are 0.15 and 0.18 m, respectively, and testing is done under steady-state conditions with the inner surface of the aluminum maintained at 250°C. In a particular test, a spherical shell of insulation is cast on the outer surface...
Can you please help me with this question. Much appreciated. So
I have a sample code, but we need to change the code in a way that
fits the problem.
A planar slab of material is initially at a temperature of 300 K. At the time t=0, microwave radiation is directed at the material, leading to internal heat generation that is uniform within the material. The sides of the slab experience negligible heat losses and a water bath maintains the...

6.1 Introduction—The design of a successful hot box appa- ratus is influenced by many factors. Before beginning the design of an apparatus meeting this standard, the designer shall review the discussion on the limitations and accuracy, Section 13, discussions of the energy flows in a hot box, Annex A2, the metering box wall loss flow, Annex A3, and flanking loss, Annex...
summarizr the followung info and write them in your own words and break them into different key points. 6.5 Metering Chamber: 6.5.1 The minimum size of the metering box is governed by the metering area required to obtain a representative test area for the specimen (see 7.2) and for maintenance of reasonable test accuracy. For example, for specimens incorporating air spaces or stud spaces, the metering area shall span an integral number of spaces (see 5.5). The depth of...
