A 3-mi section of a two-lane, two-way highway located in a mountainous terrain is to be designed to carry a peak hour volume of 750 vehicles. Using the operational level of analysis, determine the level of service at which the highway will operate for the following traffic and geometric conditions:
Lane width = 12 ft
Shoulder width = 6 ft
No-passing zones = 10 %
Directional split = 60/40
% RV = 0
% Buses = 8
% Trucks = 8
PHF = 0.95
differential leveling between benchmarks A,B,C,D, and A gives elevation differences(m) of -15.632, 32.458, 38.214, and -55.025, and distances(km) of 4,6,5, and 3 respectively.
A dispersed plug chemical reactor has an influent flow with concentration of 150 mg/L of A and a flow rate of 100 gal/min (380 L/min). The reaction is first order, The rate equation : - dC/dt = kC= -r , and the rate constant is 0.4 h^-1 .
If the dry-rodded unit weight of an aggregate is 105 lb/ft3 (1680 kg/m3) and its specific gravity is 2.65, determine the void content.
Suppose that the distance from the lake outlet to the withdrawal cannot be more than 20 mi. What should be the new volume of the lake?
calculate the depth of water in a stormwater pond resulting from a two hour rainfall event. the rainfall occurs over a 24-acre watershed at an average rate of 1 inch/hour. the runoff coefficient is 0.5.
in an air standard otto cycle , the air at the beginning of the compression stroke is at 95 kpa and 22c ,and the cylinder volume is 0.0028 m^3 . the compression ratio is 9 and 4.3 kj are added during the heat addition process
Assume that the design temperature and residence time have been established as 1300 degrees F and 0.6 seconds, respectively. The type of burner used in the process requires outside air at a mass ratio of 12:1 (air to fuel gas).
If a logit model is estimated with coefficients of -0.543 for distance and 0.0165 for commercial space (in 1000 of ft^2), how many shopping trips will be made to each of the four shopping centers?
Determine the design hourly volume for the road below, recommend the K factor first.
draw shear and bending moment diagrams determine the maximum stress on the beam (E=2.0E+11Pa) a simply supported beam AB is 5 m long carrying a uniform distributed load of 10kn/m over a 4m span
If the ultimate BOD of the mixed river water is 30mg/L, the rate constant for BOD at 20ºC is 0.6d-1, the reaeration rate constant at 20ºC is 0.8d-1, and the removal of BOD by sedimentation can be neglected
Which software do we use to calculate force and moment, and draw shear and moment diagram? I really need this software to design my structural project. Please helps me... thank you so much
