As a technician in a company that supplies glass you are required as part of your tasks to calculate and give specifications for the glass that the company designs. This information is vital for the end use of the glass and to develop and supply the correct type of glass. The company wants to install a sliding door glass for an access and ventilation that is 0.5 metres in width and has a height of 1 metre. The target thickness of the pane of glass is 0.5 cm so that it has adequate strength. The glass is installed for typical African conditions, and it is assumed that the outer surface temperature is 24°C and the inner-surface temperature is 24.5°C. You are required to calculate i) The thermal resistance and, ii) rate if heat transfer through the glass.
