Question

9. Bilbo lives in a rectangular home, 10.0m (width) x 16.0m (length) x 10.0m (height), which he maintains at a constant temperature of 23.0°C year round. Each of the outer walls, including the roof, has two sandwiched layers of uniform thickness: wood (2.0cm) and fiberglass insulation (14.5cm). Note: The thermal conductivities can found in the UsefulPhysicalQuantities file in D2L. Bilbo's House i. Determine the total surface area of Bilbo's house, excluding the floor. For simplicity, assume that the windows and doors have the same thickness and thermal conductivity as the walls. Ignore the floor (bottom) surface. 10.00m 10.00m ii. During the winter, the average outdoor temperature is 5.0°C. Find the temperature between the two layers of the outer wall. 16.00m Outer Wall Outside Inside iii. Calculate the average rate of conductive heat loss for Bilbo's house in the winter. Insulation iv. Calculate total heat loss during a 30-day winter month, in J Wood and kW/hr.

Answer 1

kindly provide the value of thermal conductivity coefficient to solve third and fourth part .

1.) Total surface area of Bilbo's house , A 2 (hb + hllo + lb = 2(10x/6)+ a 1 10xlo) + 16x10 ma - [ 320 + 200 + 160 m² 480 m2 Qji) in house The average Outdoor temperat rature is 5°c The temperature maintained 23°C .: The tempesature between the two layers of outer 23-5 AT heall 180
