3 The manufacturing process for making a 55 cm X 70 cm antiviral silver coated plastic sheet used to make a face shield involves heating the material at 400C followed by a special treatment at 360C for 20 mins. When a uniform temperature of 360C is reached within the material, the silver coated sheet is immersed into a solution at 30C. The thickness of this silver coated sheet is 9 mm. (a) What is the time at which the temperature of the sheet becomes 125C ? Properties of the sheet: Density: 8500kg/m3; Cp=0.37 kJ/kgk; thermal conductivity, K= 380 W/mK; convective heat transfer coefficient, h=110 W/W2K. (b) What is the rate of cooling after 2 mins
