A spherical furnace has an inside diameter of 6ft and an outside diameter of 8ft. The furnace shell is made of two different materials, each 6inches thick. The inner and outer section of the shell has a thermal conductivity of 0.10 BTU/hr-ft- °F and 0.2 BTU/hr-ft- °F, respectively. The inside temperature is 2, 500 °F, while the outside surface is at 150°F. Calculate the heat loss for 24 hours of operation. Express your answer in scientific notation. 1= 3ft r2= 4ft r3= 4.5ft r2= 5ft A= inner section B= outer section KA= 0.1 BTU/hr-ft- °F kB= 0.2 BTU/hr-ft- °F T1= 2500 °F T4= 150 °F

Two models of controlling boards. The 1* type has high specification for work from the 2nd type. The better type has a profit of 50$ and the other 40$ per board. The 1st type of boards requiring five as much as the 2nd needs for production and the total production are 2000 boards, the first model requires 400 min to be complete and 700 min to the second model. Write this expression with LP equations to have the maximum profit with production of each model.

Below is problem MV1 from the course pack. In an earlier assignment, you created a multiview drawing of this part. Model this part with SolidWorks, with each grid spacing equal to one inch. Create a SolidWorks drawing of this part, with Front, Top, and Right Views. Import dimensions from the SolidWorks part file, and place them on the drawing so that they can be easily read. Add a note that all dimensions are inches. Add your personalized title block that you created in Chapter 2 to this drawing. *Important: Save the drawing first as SolidWorks Drawing (filetype *.slddrw) and then as an eDrawing (filetype *.edrw)! You will upload the eDrawing in Blackboard, not the SolidWorks Drawing - the SolidWorks drawing is associated with the part file, I cannot open the sw drawing unless you also send the part file; however, l can open the eDrawing without the part file.
