1) Use range poles to establish a 2.,Sby 5m grid and determine the magnetic bearings of grid lines.
2) Carry out a 3rd order vertical control survey to establish grid levels. Given RL, of PM 732 is 113A-11,4 100
3) Calculate and tabulate the adjusted reduced levels for all grid nodes.
4) Plot the grids, noting the spot height at each grid node and draw contours (0.1m contour interval).
5) Draw a diagonal line across the contours and plot a longitudinal section (profile) of the area in question.
6) The area is to be excavated to a formation level of 90 in order to construct a multistorey building. The sides of excavation are to be vertical. Compute the volume of earthwork to be excavated.
Design a hollow steel shaft with an inside diameter 1/3 that of the outside diameter. The shaft transmits 200 kW at a speed of 20 Hz. The allowable shearing stress is 55 MPa, and the allowable angle of twist is 1 degree per meter of length.
In water and wastewater treatment process a filtration device may be used to remove water from the sludge formed by the precipitation reaction. The initial concentration of sludge from softening reaction is 2% (20,000 mg/L) and the volume of sludge i..
A centrifugal pump is used to pump Vodka (S.G. 0.8) at a rate of 20 gallons per minute to the top of a 30 foot tall tank. The owner wants to use the same pump to pump orange juice (S.G. 1.1). Explain how this change in fluid will affect:
The temperature of the poker at the third points of the poker using three elements of equal length. Use the finite element method. You may use Mathcad to solve this problem. If you do, please show all work and add comments to the Mathcad solution ..
Twenty years of annual maximum rainfall depths are given below. Determine the rainfall depths to be used for storm structure design for the following annual return periods: 2, 5, 10, 25, 50, & 100 year.
An equal tangent vertical curve conects an initial grade of -3% and a final grade of +1% and is designed for 60mi/h. The PVI is at station 250+50 and elevation 732 ft. What is the station and elevation of the lowest point on the curve
an embankment for a highway 30m wide & 1.5m in a compacted thickness is to be constructed from a sandy trucked from a borrow pit.
Indoor Air quality is greatly affected by Radon, which can cause lung cancer. When we moved to Colorado, we tested the house for Radon and installed a radon mitigation system.
Suppose you are told that a process must achieve a 2.7 log removal of Giardia cysts. What does that mean in terms of % remaining and % removal
A line of sheet piling is driven 4m into a firm clay and retains, on one side, a 3m depth of fill on top of the clay. Water table level is at the surface of the clay. The unit weight of the fill is 18kN/m3 and the saturated unit weight of the clay is..
The proposed highway has two tangents of bearings N 45Degrees 54' 36" E and N 1 Degree 22' 30" W. The highway design engineer, attempting to obtain the best fit for the simple circular curve join these tangents, decides that the external is to be ..
