Caterpillar Inc. would like to upgrade current fabrication techniques on its Excavator assembly line. Upgrades include state of the art equipment designed to automate specific portions of fabrication which have been very labor intensive in the past. To meet current floor plan space, four equipment design alternatives have been considered, which will have capital investment and annual operating expenses as shown in the table below. Assuming a useful life of 8 years for each design, no market value, and a desired MARR of 12% per year, determine which design should be selected based on the IRR method (incremental rate of return analysis).

The long ranger is riding through a sandstorm. Does his mask (a bandanna that covers his nose) significantly decrease the amount of sand he breathes in? assume the bandanna is made of fibers, each 300 μ in diameter. They are woven in a simple weave that blocks 75 % of the projected area; the remaining 25 % is open, with holes up to 75 μ in diameter. For the purpose of this problem, the bandanna may be considered equal to a single row of parallel fibers, each 300 u in diameter, with 75 % of the flow area blocked and 25 % open. The gas velocity approaching the cloth as he breaths is 1 m/s. a). Estimate both the collection efficiency for 10 u particles and the cut diameter for bandanna used as a filter
