A window has dimensions of 1.7 m by 2.75 m and is made of glass 7.25 mm thick. On a winter day, the outside temperature is 23° C while the inside temperature is a comfortable at 17° C. (k of glass =0.165W/m.K) (1.5+1.5+2= 5marks) Calculate the following: a) the area of the window in square metres b) the temperature gradient (AT/Ax)in kelvin/metre c) the rate of heat lost through the window by conduction in watts/metre kelvin
