10-36 A shell-and-tube heat exchanger has condensing steam at 100°C in the shell side with one shell pass. Two tube passes are used with air in the tubes entering at 10°C. The total surface area of the exchanger is 30 m2 and the overall heat-transfer coefficient may be taken as 150 W/m2 .°C. If the effectiveness of the exchanger is 85 percent, what is the total heat-transfer rate?

Problem 3: A small gearing system in your brand-new 3D printer fails as you were printing, leading to an overload in the motor and a fire in your home. The fire spreads, burning half of Everglades National Park in the worst environmental disaster in US history. The printer company blames you! Stating that you must have been misusing the printer some- how. Use your engineering knowledge to "show those jerks you mean business!" You investigate and find a serial number on the gears and type it into Google, finding the company that manufactures the gears. Their website provides some info that this series of gear is made from AISI 4340 steel and the yield strength is 125 kpsi. Assuming each gear tooth acts as a small cantilever, prove to the 3D printer company that they are liable for the fire. oct # Gear Information Gear radius (r): 1.00 in Tooth length (1): 0.15 in Tooth height (h): 0.15 in Tooth thickness (b): 0.1 in Angular velocity (w): 0.1 rad/s Motor Information Power (H): 0.009 hp 1…

Manufacuring Processes An electro chemical machining (ECM) operation is employed too cut a square hole in a copper plate of 18 mm thickness. The dimensions of the hole is 20 mm on each side, however, the electrode dimension shall be slightly less than 20 mm to allow for overcut, and its shape includes a hole in its center to permit the flow of electrolyte and reduce the area of cut. The frontal area of electrode is 180 mm2. The specific removal rate for copper is C = 7.35 x 10-2 mm3/A-s. The applied current is 950 A. At 90 % efficiency, determine the time required to cut a hole of required dimensions.
