#questi1.) A house has 0.5 cm thick single-pane glass window 2m by 1.5m .The temperature is 20 degrees Celsius and the outside temperature is -20 degrees Celsius .If there is an air layer on both the inside of the glass each with an R-factor of 0.1m squared K/W, determine the heat transfer rate through the window if Kglass=1.4 W/m.K

2.)An electronic gizmo with a surface area of 75mm squared generates 3W of heat. It is coded by convection to air maintained at 25 degrees Celsius. If the surface temperature of the gizmo cannot exceed 120 degrees Celsius, estimate the heat transfer coefficient needed.
