A wood fire with a temperature of 1110F is at the other side of a 10 square ft wall that has a 6-inch layer of firebrick, 3-inch layer of concrete, and 6 inches of regular bricks. The thermal conductivity in Btu of each material is as follows: 0.27, 0.76, and 0.98 respectively hr-ft-° Solve for the heat conducted through this wall and the temperatures measured between the layers if the temperature at the other end of the wall is 150F?

4 2 MOHR CIRCLES PROBLEM You've been working in the lab to determine the strength of an altered granitoid which hosts mineralization. The company you work for wants to start a deep underground mine in the region and it is imperative that the strength of the altered granitoid is well characterized. You conduct a series of experiments on the granitoid to develop a Coulomb failure criterion for the altered granitoid. All of your experiments were conducted in dry conditions (i.e., no pore fluid pressures). Plot up your 3 experiments as Mohr circles, fill in the table below, and determine the Coulomb failure criterion for the altered granitoid.

I do not understand how to read the graph to determine what ? is. Please help me read the graph to understand it. The temperature distribution in a flat slab needs to be studied under the conditions shown in the table. The ? in the table indicates insulated boundary and Q is the distributed heat source. In all cases assume the upper and lower boundaries are insulated. Assume that the units of length, energy, and temperature for the values shown are consistent with a unit value for the coefficient of thermal conductivity.

My buddy is starting to get hypothermic (body temperature 306 K) during an epic backcountry ski adventure. Since I'm quite warm (body temperature 310 K), I decide to get in a sleeping bag with him to try and warm him up. What heat transfer mechanism will be most responsible for heating him up? For simplicity, ignore any internal temperature differences across my body (that is, assume my skin temperature is also 310 K). Use numbers to support your answer (for human skin, you can use the following values: surface area A = 1:50 m2, emissivity = 0:970, thickness d = 0:0250 m, thermal conductivty 0:200 JmsK)
1-) Die casting is a metal casting process that is characterized by forcing molten metal under high pressure into a mould cavity. A circular die (k = 150 W/mK, T = 125 °C) is used to drill a hole (D = 0.5 m) along length L = 3 m through a cylindrical metal (D = 2 m) as shown in the figure. A cooling fluid (k = 0.6 W/mK) passes through the hole during the process to keep the inner surface temperature of the hole to 85 °C. In the meantime, the outer surface temperature of the cylinder is held at 30 °C. The hole is drilled eccentrically (not in the origin of the cylinder, 0.1 m perpendicular distance) as shown in the figure. If the heat loss through the cylinder is XY kW during this process, what is the thermal conductivity of the cylindrical metal? (Take the heat loss value XY as a 49 2m 0.1m %3D 3m
