Two flat infinite slabs, each 5 m thick, are each initially uniform in temperature, with one being at 0° and the other at 20°. At t=0, the two slabs are stacked together (the warmer one at larger y) and both the top and bottom surfaces of the stack are kept at 0°. Find the temperature in the stacked slabs as a function of y and t for t > 0. Write out the heat flow equation, find the general solution, and the specific solution for this arrangement.
A thick concrete wall having a uniform temperature of 50oC is suddenly subjected to a stream of water so that the surface temperature is suddenly lowered to 15oC.

Steaks (2 cm thick, k = 0.45 W/m - °C, « = 0.91 x 107 m2/s) usually have an original temperature of 25 °C. They will be cooled in a refrigeration room. The said room has a temperature of -11 °C. The heat transfer coefficient on both sides of the steak is 9 W/m2 - °C. How long will it take for both surfaces of the meat to be cooled to 2 °C? Assume the geometry of steaks to be a flat slab.

(a) A length of brass piping is 30 m long at a temperature of 18°C. When hot water flows through it the temperature of the pipe rises to 70°C. Determine the length of the hot pipe if the coefficient of linear expansion for brass is 18 x 10-6 K-¹.
An insulated vertical cylindrical vessel of cross- sectional area A = 0.12 m² contains 20 mol of He gas at To = 300 K and Po= 0.5 bar. It is capped by a movable piston of mass m = 150 kg supported from the ceiling by a wire. The top of the vessel is open to the atmosphere (Patm= 1 bar, Tatm= 300K). The wire is cut and the weight falls and com- presses the gas. Patm 160 E Wir og SLOWA He gas 1019 (a) Obtain the pressure and temperature of the gas a short time after the wire has been cut, when a negligible amount of heat transfer has taken place. Comment on whether your solution takes into account the inevitable oscillations of the piston around its equilibrium position before it comes to rest. mut Ispl (b) After a long time, the He gas thermally equilibrates with the environ- ment by heat transfer through the piston. How much heat is exchanged with the environment during this process? Helium can be considered an ideal gas at all conditions of interest, with C₁=3R/2. INST
