Stephanie S Colleagues At Beacon Lighting Bankstown Are Observing The Operation Of An Incandescent Light Globe Beaming I 1 (15.92 KiB) Viewed 13 times

Stephanie's colleagues at Beacon Lighting Bankstown are observing the operation of an incandescent light globe beaming in the distance. The specifications show the bulb's electrical filament made of tungsten converts 20% of the energy it receives into light, and the remainder into heat. When she switches the 100mm100mm diameter spherical bulb on, it heats up rapidly as a direct result of energy transfer into the filament which then radiates and convects out into the surrounding environment. To reduce the temperature of the 75W75W light globe, it is strategically placed in front of an air conditioner that blows air at a temperature of 30∘C30∘C and a velocity of 2.5m/s.2.5m/s. The surrounding surfaces in the vicinity are stable at 30∘C30∘C and the emissivity of the bulb is 0.92.0.92. Determine a quartic equation for the equilibrium/steady-state surface temperature of the bulb and solve it (using an online quartic equation solver).Assume an initial surface temperature estimate of the bulb to be 100oC100oC.
