Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.

Hello, I have been having trouble analyzing the following situation related to the field of Heat Transfer; I am needing to find the heat transfer rate through the given wall in Watts (shown in attached image): A wall consists of four different materials, A, B, C, and D as shown. The thermal conductivities of A, B, C, and D are 1, 5, 10, and 15 W/(mK), respectively. The inner surface of the wall is maintained at 60 oC, and the outside temperature is 20 oC. The convective coefficient for the outside air is 20 W/(m2K). The area of A, B, and C is 0.3 m2, and each is of equal thickness. Area D has an area of 0.1 m2 and thickness of 45 cm. I know some equations that can be used to solve this problem using the thermal circuits concept, but those equations require knowing the additional information about the temperature of the inside air or the surface temperature of the outside wall. Could you please help me determine what methods needed to solve this problem that I am missing? Thank you.
The thermal conductivities of human tissues vary greatly. “Fat” and “skin” have conductivities of approximately 0.200 W /m 0K and 0.0200 W /m 0K, respectively, while other “tissues” inside the body have conductivities of approximately 0.500 W /m 0 Assume that between the core region of the body and the skin surface lies a “skin” layer of 1.00mm, a “fat” layer of 0.500 cm., and 3.20 cm. layer of other “tissues”. Find the rate of energy loss when the core temperature is 37.00C and the exterior temperature is 0.000 Assume a body area of 2.00 m2. (Both a protective layer of clothing and an insulating layer of unmoving air are absent).
