- An industrial oven, like the one shown in the figure, is in permanent production for the thermal treatment of ferrous materials. It is interesting to know the energy efficiency of the oven, which is calculated as a percentage of the heat of the burner, based on the power caloric value of the fuel, according to its technical data. Calculate the thermal efficiency of the oven. The complete information and the tables for the calculations are in the attached image.arrow_forwardI want to know how much heat the tube lost due to the material it is made of aluminum or steel.

During the design of spherical pressure vessel for space programs, a primary criterion is the mass of the vessel (which determines how much it costs to put it into the orbit). Given the stress in a thin walled spherical vessel is tensile and given by: Pr 2t where P is the pressure in the vessel, r is the radius and t is the wall thickness. For safety, materials will experience stress smaller that yield stress by a safety factor N. 10-1 Show that the minimum mass of the pressure vessel will be m= 2Νπ Pr' where p is the density of material. ys Given the data in Appendix B1 and B4 in the textbook, select the material (from following table) that will result in the lightest possible pressure vessel.
