A 98% efficient ESP is to treat a gas stream flowing at 5000 m^3/min. If the effective drift velocity is 6.0 cm/s, calculate (a) the plate area (required and actual in m^2 and (b) the number of plates if each plate is 6 m by 10 m, and there are 3 sections in the direction of flow. Assume that the ESP of Problem 5.1 is built with an actual collection area of 5400 m^2. Now suppose that the actual drift velocity turns out to be 5.0 cm/s and the actual gas flow turns out to be 5500 m^3/min. Calculate the actual efficiency. An ESP must treat 500,000 acfm with 99% efficiency. Assuming an effective drift velocity of 0.4 ft/sec, calculate the required plate area in ft^2, and the number of plates if each is 20 ft tall by 10 ft long, and there are 4 sections in the direction of flow.

Ashielded metal arc-welding operation is accomplished in a work cell by a fitter and a welder. the fitter takes 5.5 min to load components into the welding fixture at the beginning of the work cycle, and 1.5 min to unload the completed weldment at the end of the cycle. the total ength of the weld seams 1200 mm, and the travel speed used by the welder averages 300 mm/min. every 600 mm of seam length, the welding stick must be changed, which takes 0.8 min. while the fitter is working, the welder is idle (resting): and while the welder is working the fitter is idle. (a) determine the average arc-on time as a fraction of the work cycle time. (b) how much improvement in arc-on time would result if the welder used flux-cored arc welding (manually operated), given that the spool of weld wire must be changed every 10 weldments, and it takes the welder 5.0 min to accomplish the change? (c) what are the production rates for these two cases (weldments completed per hour)? attach your work and solutions.
