1.An open traverse that runs from A through H has the following deflection angles: B = 6o25' R; C = 3o54' R; D = 11o47' R; E = 20o02' L; F = 7o18' L; G = 1o56' R. If the bearing of AB = N 20o40' E, compute the bearings of the remaining sides.
2.A 150-mL sample from a lake was used to determine TSS. A rinsed and dried filter weighed 0.3588 grams before the sample was filtered and then weighed 0.3630 grams after the sample was filtered and being at dried at 103C. What is the TSS for this sample?
3.A BOD5 test sample of river water has the following test data. DO on day 0 = 7.9 mg/L. DO on day 5 = 2.3 mg/L. What is the BOD5 of the river water?
4.A 250 cubic meter reaction tank contains a waste water having an ultimate BOD concentration of 755 mg/L. If the BOD reaction rate constant is -0.352/day, how much BOD is remaining after 12.0 days?
What kind of soil labs are good for the construction which is underlying the wet clay is dense sand. For example, compaction, and so on.
Water flows through a 4-cm pipe, wrought iron, horizontal pipeline 50-m long from point A to B, and contains a fully opened gate valve and two elbows (R/D = 4).
A four- lane undivided multilane highway ( two lanes in each direction) has 11- ft lanes and 5- ft shoulders. At one point along the highway there is a 4% upgrade that is 0.62 mi long. There are 15 access points along this grade.
A 2-kg block slides on the smooth circular path (Quadrant One of full circle, block moving left to right). If it is released from rest when theta=0 degrees, determine the force it exerts on the path when it arrives at Point A
If a unit mass of groundwater accelerates from rest to an average linear velocity of 1 m per year and climbs a vertical distance of 1 m, compare the ratio of kinetic energy to the potential energy of the unit of groundwater.
The car's gear reduction ratio is 3.5 to 1, driveline efficiency is 90%, driveline slippage is 3.5%, and the road-wheel radius is 15 inches. What will the car's maximum acceleration be under these conditions on a level road
