The vertical distance from point A to the center of the theodolite is 4.66 feet. Point B which is 900.00 feet (slope distance) away from the center of the theodolite is observed at a zenith angle of 84°4530". What is the elevation of B to...
A level has been found to be out of adjustment. When a two-peg test and adjustment were made, two stakes (A and B) were set 215 ft apart. When the instrument was set up midway between A and B, the rod readings were 4.26 on A and 5.15 on B. When the instrument was set up very close to A, the rod readings were 6.02 on A and 6.79 on B. With the instrument remaining near A, the crosshairs should...
7. An elevation difference measurement by a total station is (a) is from the ground point at the total station to the ground point at the prism computed from only slope distance and zenith angle (b) requires the horizontal circle to compute the elevation difference (c) requires sighting a known elevation on a backsight (d) usually requires height of instrument and height of target to be correctly derived 8. A horizontal angle at 2 from 1 to 3 is 65-08-10,...
Intriduction to Surveying cfferential leveling, the elevation of a turning point is usually found by: Adding the foresight to the current H.I. Subtracting the foresight from the current H.L Subtracting the backsight from the H.L Adding the backsight to the elevation of the benchmark None of the above A benchmark (B.M.) is a point of known elevation that should remain in place for only one week. TRUE FALSE 18 To obtain the elevation of a furning point, add the level...
A reservoir has a lower water level set at 200 ft. The pump is set at an elevation of 190 ft. It was determined through analysis that an existing pump is experiencing cavitation. Which of the following will decrease the risk of cavitation? Select all that apply. A) Raise the elevation of the pump. B) Increase the temperature of the water. C) Decrease the diameter of the suction pipeline. D) Operate the pump at a lower speed. E) Increase the...
