In determining the difference between points A and B, the inclined distance was measured to be 157.65 ft. The transit was set u on point A. The height of its transverse axis was 5.2 ft about point A. The instrument had an index error of +4'. A rod was held on point B and the telescope was inclined so the horizon cross line intersected the rod at 5.2 ft mark. If the reading on the vertical limb of the transit was + 25 degrees 19', what is the difference in elevation between the two points?
A small truck is to be driven down a 4% grade at 70mi/hr. The coefficient of road adhesion is 0.95, and it is known that the baking efficiency is 80% when the truck is empty and decreases by one percentage point for every 100 lb of cargo added.
Gaseous oxygen (99% pure, molar basis) is to be produced at a rate of 350ft^3/hr in a Linde single column plant. The column operates at a pressure of 1 atm. Air leaves the compressor at a pressure of 10 atm.
