Determine the cycle time for a single engine scraper rated at 21 cy heaped that is used to haul material from a pit to a fill 900 ft away under severe conditions. The average haul speed will be 14 mph and the average return speed will be 20 mph. Assume that at an average speed of 5 mph, that 200ft is required both to accelerate and decelerate. The operating efficiency to a 50-min hour. It will take 0.80 min to load this scraper.
Determine the minimum necessary clearance height of the overpass and the resultant elevation of the bottom of the overpass over the PVI. (ignore the cross-sectional width of the overpass)
Determine the factor of safety for a 9 foot long hollow steel column 3.5 inches on a side that has a wall thickness of 0.225 inches and is loaded with a 22 kip load.
A gravity thickener receives 33.000 Lpd of wastewater sludge and increases the solids content from 3.0% to 7.0% with 90% solids recovery. Calculate the volume of thickened sludge.
