- Definition radiation process in nanofluid and give some exampleThe tungsten filament of an incandescent light bulb has a temperature of approximately 3000 K. The emissivity of tungsten is approximately 1/3, and you may assume that it is independent of wavelength. To increase the efficiency of an incandescent bulb, would you want to raise or lower the temperature? (Some incandescent bulbs do attain slightly higher efficiency by using a different temperature.)Describe thermal radiation in nanofluid
- A spherical radiator has a radius of 3ft and emissivity of 0.5. If radiates 6000 Btu/hr of heat at 3000R, what is the temperature of a surface affected by its radiation?A thin tungsten filament with a length of 1.47 m radiates 60.2 W of power in the form of electromagnetic waves. A perfectly absorbing surface, in the form of a hollow cylinder with a radius of 5.09 cm and a length of 1.47, is placed concentrically with the filament. Calculate the radiation pressure acting on the cylinder. (Assume that the radiation is emitted in the radial direction, and neglect end effects.)Fused quartz transmits 90 percent of the incident thermal radiation between 0.2 and 4µm. Suppose a certain heat source is viewed through a quartz window. What heat flux inwatts will be transmitted through the material from blackbody radiation sources at (a)800◦C, (b) 550◦C, (c) 250◦C, and (d ) 70◦C? (Holman, 2002)

The filament of a 100-watt bulb maybe considered a black body radiating into a black enclosure at 80 deg C. Considering only radiation, calculate the filament temperature in deg C if the filament is 0.10mm and the length is 6cm.
