(25pts) Consider a 1.2-m-high and 2-m-wide glass window whose thickness is 6 mm and thermal conductivity is k 0.78 W/m °C. Determine the steady rate of heat transfer through this glass window and the temperature of its inner surface for a day during which the room is maintained at 24°C while the temperature of the outdoors is-5°C. Take the convection heat transfer coefficients on the inner and outer surfaces of the window to be h 10 W/m2 °C and h...

A 15 cm diameter, 2 cm thick sight glass installed in the wall of a glass fired boiler allows the operator to observe conditions inside the boiler during operation. During normal boiler operation, the inside surface of the sight glass is 130C. Due to natural convection current in the warm boiler room, air at 35C flows vertically across the outside surface of the sight glass, giving the heat transfer coefficient of 25 ?/?2 ?. The sight glass is made of...

A picture window has dimensions of 1.40 m×2.50 m and is made of glass 5.30 mm thick. On a winter day, the outside temperature is -15.0 ∘C , while the inside temperature is a comfortable 21.0 ∘C . Part A At what rate is heat being lost through the window by conduction? Part B At what rate would heat be lost through the window if you covered it with a 0.750 mm-thick layer of paper (thermal conductivity 0.0500 W/m⋅K)?
