A picture window has dimensions of 1.05 m by 2.35 m and is made of glass 7.75 mm thick. On a winter day, the outside temperature is 23 C while the inside temperature is a comfortable at 18 C. (k of glass =0.145W/m.K) ((a*1.5)+(b*1.5)+(c*2.0) = 5marks) Calculate the following: a) the area of the window in square metres b) the temperature gradient (AT/Ax)in kelvin/metre b) the rate of heat lost through the window by conduction in watts/metre.kelvin
