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.
An underwater sonar that maps the ocean bathymetry is encapsulated in a sphere with a diameter of 85 mm. During operation, the sonar generates heat at a rate of 300W. What is the sonar surface temperature when it’s located in a water column where the temperature is 15o C and the water current is 1 m/sec? The sonar was pulled out of the water without turning it off, thus, it was still working. The air temperature was 15o C and the air speed was 3 m/sec. What was the sonar surface temperature? Was there any reason for concern?
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.

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.

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 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
Please show all steps not Ai generated they have been wrong and I need to understand whats goin on. A steel sphere (AISI 1010), 100 mm in diameter, is coated with a dielectric material layer of thickness 2 mm and thermal conductivity 0.04 W/m • K. The coated sphere is initially at a uniform temperature of 500°C and is suddenly quenched in a large oil bath for which To = 100°C and h = 3000 W/m • K. Estimate the time required for the coated sphere temperature to reach 150°C. Hint: Neglect the effect of energy storage in the dielectric material, since its thermal capacitance (pcV) is small compared to that of the steel sphere.
