Question: A basement for a certain home is 4 5 m with a ceiling height of 3 m. The walls are concrete having a thickness

A basement for a certain home is 4 × 5 m with a ceiling height of 3 m. The walls are concrete having a thickness of 10 cm. In the winter the convection coefficient on the inside is 10 W/m2 ∙ ºC and the soil on the outside has k = 1.7 W/m· ºC. Analyze this problem and determine an overall heat transfer coefficient U defined by qloss = UAinside(Tinside − Tsoil). Determine the heat loss when Tinside = 26ºC and Tsoil = 15ºC.
