A furnace is required to sinter powder-metal parts. It operates continuously at 650 °C while the parts are fed through on a moving belt. You are asked to select a material for furnace insulation to minimize heat loss and thus to make the furnace as energy-efficient as possible. For reasons of space the insulation is limited to a maximum thickness of x = 0.2 m. (a) List the function, constraints, objective and free variable. (b) Derive a material index for selecting the material for the insulation.

1.63 Liquid oxygen (LOX) for the space shuttle is stored at 90 K prior to launch in a spherical container 4 m in diameter. To reduce the loss of oxygen, the sphere is insulated with superinsulation developed at the U.S. National Institute of Standards and Technology's Cryogenic Division; the superinsulation has an effective thermal conductivity of 0.00012 W/m K. If the outside temperature is on the average and the LOX has a heat of vaporization of 213 J/g, calculate the thickness of insulation required to keep the LOX evaporation rate below 200 g/h.
A block of rubber of size 1” x 3” x 1.5” thick is confined between parallel walls of a steel block spaced precisely one inch apart (as shown in the sketch below, where R is the rubber block and S is the steel block). A force of 6500 pounds is applied to the top surface of the rubber block, with surface dimensions of one inch by three inches. If Poisson’s ratio for the rubber ν = 0.45 and modulus of elasticity for the rubber E = 10,000 pounds per square inch, determine the stress acting on the sides of the rubber that are in contact with the parallel walls of the steel block
It is designed in such a way that the internal temperature of a commercial heat treatment furnace can reach up to 165 oC. All surfaces of the furnace consist of firebrick (10 cm), insulation material and sheet metal (3mm) from the inside out. Given that the outdoor temperature is 22 oC, the outer sheet will be allowed to go up to 35 oC, which is a temperature that will not be disturbed by hand contact. In this case, determine the insulation material thickness to be used. Insulation material thermal conductivity coefficient is 0.066 insulation W / m oC, 60 W / m oC for sheet metal and 115 W / m oC for firebrick. Indoor heat transfer coefficient will be accepted as 25 W / m2 oC and 12 W / m2 oC for outdoor environment.
In 2012, a new fiber-optic cable of handling 40,000 telephone calls simultaneously was laid under the Pacific Ocean from California to Japan, a distance of 13,300 km. The cable was unreeled from shipboard at a mean temperature of 22oC and dropped to the Ocean floor having a mean temperature of 5oC. The coefficient of linear expansion of the cable is 75×10-6 /degree celsius. Determine the length of cable that must be carried on the ship to span the 13,300 Km. Also, find the percent change in length

You are designing a small heatsink to cool a high-powered IC on a control unit PCB. The IC puts out 40,000 W/m2 and has a size of 40mm x 20mm. A fan blows 40 degrees C air across the IC at a speed of 4 m/s. The IC is well insulated on its back face. If the convection coefficient is 62 W/m2K, what is the surface temperature of the IC?
Yes it is hard but please I need help with this A horizontal 8 cm OD pipe carries steam at 150°C through a room at 17°C. The pipe is covered by a1.5 cm layer of magnesia insulation. What is the heat loss per meter of the pipe?• For this configuration if a horizontal cylinder, NuD = f (RaD, Pr) can be found using equation 8.28• I assume since material and thickness of the pipe inside the insulation are not given, nor is any flow data onthe steam that these resistances are negligible.• The temperature of the outer insulation is not initially known. I guessed it and used a circuit diagram with tworesistances to find Q, then used one circuit to find the wall temp, and iterated. I updated my material propertieswith my wall temperature changes. It converged quickly.• My answer is 5-10% higher than the books. Not sure why.

In a quenching process, a copper plate of 3 mm thick is heated up to 350°C and then suddenly, it is dropped into a water bath at 25°C. (1) Calculate the time required for the plate to reach the temperature of 50°C. The heat transfer coefficient on the surface of the plate is 28 W/m2-K. The plate dimensions may be taken as length 40 cm and width 30 cm. (2) Also calculate the time required for infinite long plate to cool to 50°C. Other parameters remain same. (3) Calculate the heat transfer rate loss of the plate when it is at 50°C. Take the properties of copper as: CP = 380 J/kg-K, ρ = 8800 kg/m3, k = 385 W/m-K
