1.A horizontal curve on a single-lane highway has its PC at station 124 + 10 and its PI at station 131+ 40. The curve has a superelevation of 0.04 ft/ft and is designed for 65mph. What is the station of the PT?
2.An 18in. diameter sewer is placed on a grade of 1.5ft/1000ft. What are the discharge and the flow veloctiy when the pipe is full?
As a consulting engineer you are hired to evaluate the operation and the unit processes within the plant and make recommendations for improvements. You are asked to consider the following units.
A well of 0.4 m diameter fully penetrates a 25 m thick confined aquifer of coefficient of permeability of 12m/day. The well is located in the center of a circular island of radius 1 km.
Verify that the displacement response of the system - single-degree-of-freedom model below is subject to the pulse loading
suppose there are 10 pieces of paper in a hat. Each piece of paper has a digit 1 through 10 written on it. Each number is written only once. You reach in the hat and select a piece of paper. What is the probability that the paper has either a 3 or..
The service loads on a steel truss member are PDL: 120 kips (tension), PLL =240 Kips (tension), PWL = 200 kips (tension/compression). Steel properties are Fy = 46 ksi, Fu = 58 Ksi. Using the tables in the AISC manual, make a preliminary selection of ..
Soil material is being assessed as a possible liner for a sanitary landfill. A soil core was collected and brought to the laboratory. A 10-cm tall section of soil has 2 cm of water continuously ponded on it. The area of the core surface is 78 cm^2..
using darcy's law compute the quantity of flow, seepage velocity and contaminant loading of the river. ground water is flowing through unconfined uniform 3m thick sand aquifer and discharging to river.
On a single graph, plot the PDFs if E is assumed to be normally, lognormally, and gamma distributed. Plot the PDFs for E values between 10,000 and 50,000 kips/in2. Make sure to label the axes and use a legend to label the curves.
An activated sludge system treats 1500 m3/day of raw wastewater with a BOD of 250 mg/L. The reactor volume is 375 m3. The kinetic parameters were determined to be: x = 3 day-1, Y = 0.55 kg SS/kg cells, and Ks = 150 mg/L.
Cylindrical, steel bar stock (density = 7833 kg/m3, Cp = 0.465 kJ/(kg C)) of 10-cm diameter is heat-treated by drawing it at a velocity of 3 m/min through a 6-m-long furnace maintained at 900C.
You have a steel alloy with a 1.00 wt% carbon content that is cooled to room temperature. What is the eutectoid cementite content of this sample
