QUESTION 1.

The foregoing analysis is conservative since heat transfer at the irradiated surface due to convection and net radiation exchange with the environment have been neglected. If the emissivity of the surface and the temperature of the surroundings are assumed to be = 1 and T. sur = 298K, ()10 Best Gas Masks Reviewed of 2020 | GuidesMagIt acts as a sealed cover over the mouth and nose, but it can also cover numerous vulnerable tissues of the face including the eyes. Gas masks can also be respirators, but they are often only referred for military equipment, mostly for field protective mask. The gas mask cannot protect its user from gas that is absorbed by the skin.Improvement of Aluminium Film Adhesion on PMMA Using During the electron beam evaporation for deposition of an aluminium film, high-speed electrons decelerate when they bombard the material and part of the electron energy contributes to radiation. Due to the high sensitivity of polymethyl methacrylate (PMMA) to such radiation (in UV), the PMMA surface is degraded. This results in a weak surface of PMMA layer and decreases film adhesion.
