A picture window has dimensions of 1.40 m×2.50 m and is made of glass 5.10 mm thick. On a winter day, the outside temperature is -15.0 ∘C , while the inside temperature is a comfortable 21.0 ∘C .

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)?

**I'm getting 6713 W but it saying im wrong. Please help

A steel hot-water tank of cylindrical shape has an inside diameter of 0.600 m and inside height of 1.40 m. The tank is enclosed by a 5.00 cm thick insulating layer of glass wool whose thermal conductivity is 0.0350 W / (m·K). The insulation is covered by a thin sheet metal skin. The steel tank and the sheet metal skin have thermal conductivities that are much greater than that of the glass wool. How much electrical power (W) must be...
