An 1100 ft. straight line route survey, which had PI's at3+81.27 (I = 12o30') and 5+42.30 (I = 10o56'), laterhad 600 ft radius simple curves inserted at each PI. Compute the following:
a)Curve data for each curve: Da, T, L, LC, E, and MO
b)stations of the PC and PT for each curve
c)the equation of chainage (what is the last station after the curves have been inserted)
When working with flow through pipes , engineers typically have to determine if the flow is laminar or turbulent. Compute the Reynolds number for each of the cases below and determine if the flow is laminar or turbulent. Assume all of the conduits..
Find the limiting length of an offset so that the displacement of a point on paper is may not exceed 0.025 centimetres.The offset was laid 3 degree out from it's true direction and the scale was 10m to 1cm.
A saturated clay deposit is vane-tested in-situ. A torque of 30Nm is required to shear the clat. The vane is 40mm wide by 100mm long. What is the undrained shear strength of the clat in kPa
At the same instant the frame h, not the horizontal blade, rotates about a vertical axis with a constant angular velocity w=0.9 rad/s, measured relative to h
The turbidity of the water ranges from 30 to 60 NTU, alkalinity exceeds 100 mg/L, hardness is about 50 mg/L as CaCO3, and the water also contains regulated synthetic organic compounds resulting from industrial discharges.
How far apart must two 18 m diameter tanks be placed such that their stress overlap is not greater than 10% of the contact stress at depths of 10, 20, and 30 m
Given a horizontal curve of radius 1400 feet, a central angle= 46 degrees 21 minutes located at PI 50 plus or minus 00.00 on the centerline of a two-lane road with 12-foot wide lanes,
The heat exchanger consists of 12 m of copper tubing that is 2 cm in diameter with 19 return bends. The flow rate is 3 x 10-4 m3/s. Water enters at 20 C and exits at 80 C. The elevation difference between the entrance and the exit is 0.8 m.
For the purposes of assessing an economy's growth performance, which is the more important statistic, real GDP or nominal GDP? Why?
A new interstate highway is being built with a design speed of 70 mi/h. For one of the horizontal curves, the radius (measured to the innermost cehicle path) is tentatively planned as 2500 ft. What rate of superelevation is required for this curve
Calculate the compressive stress (in psi) for a 6-in diameter by 12-in high concrete test specimen if the total deformation under load is 0.015 in. Calculate the total load on the test cylinder stress.
A cylinder with a 6.0 in., diameter 12.0 in. height is put under a compresive load of 150 kips. The modulus of elasticity for this specimen is 8000 ksi and Poisson's ratio is 0.35. calculate the final length and the final diameter of this specuman..
