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 bur…

Chapter 2, Problem 123P

Consider a spherical shell of inner radius r1 and outer radius r2 whose thermal conductivity varies linearly in a specified temperature range as k ( T ) = k 0 ( 1 + β T ) , where k 0  and  β are two specified constants. The inner surface of the shell is maintained at a constant temperature of T1, while the outer surface is maintained at T2. Assuming steady one-dimensional heat transfer, obtain a relation for (a) the heat transfer rate through the shell and (b) the temperature distribution T(r) in the shell.

12-217. The block B is sus- pended from a cable that is at- tached to the block at E, wraps around three pulleys, and is tied to the back of a truck. If the truck starts from rest when ID is zero, and moves forward with a constant acceleration of ap = 0.5 m/s², determine the speed of the block at D the instant x = 2 m. Neglect the size of the pulleys in the calcu- lation. When xƊ = 0, yc = 5 m, so that points C and D are at the Prob. 12-217 5 m yc =2M Xp
