1. An existing urban freeway with 4 lanes in each direction has the following characteristics:
   • Peak hour volume (in peak direction) 7,070 veh/hr
   • Trucks: 10%,
   • 2,012 vehicles observed in the peak 15-minute time period
   • Lane width = 11’
   • 4’ right side lateral clearance
   • 1.8 ramps per mile
   • Rolling terrain

Determine the LOS in the peak hour.  Clearly show your results for freeflow speed, demand flow rate, capacity, mean operating speed, and density along with the LOS.

Write a function script DirCos.m that takes a vector (any row or column array) as the argument and returns the direction cosines for that vector. This is for a MatLab script

) In the calculation of gradually varied water surface profiles; a. When should calculations be done in downstream to upstream order, instead of upstream to downstream order? b. What are some fundamental differences between the Standard Step vs Direct Step methods?

Compare and contrast the open traverse, closed loop traverse, and link traverse.

List four key sections of the Clean Water Act for watershed management, then briefly describe how each one you chose can assist with improving the physical and or biological condition(s) of the watershed.

Calculate discharge required for irrigation (Irrigation demand) for given condition. Also design well diameter to pump calculated discharge for the soil of hydraulic conductivity 8.42 m/d of unconfined aquifer. Observation well, which is about 200 ft from well shows constant water table of aquifer is 100 ft. You are allowed to draw-down maximum 60 ft of water table when pumping discharge

Comparison of two hypothetical cases:

Project 1: New construction of a highrise building in Wall Street, Manhattan, NYC.

Project 2: New construction of LNG tanks in Cameron, Louisiana

Two projects are greatly different in terms of project type and location. Discuss and compare unique impacts on the environment and public that may occur in each project.

2. Current codes indicate the maximum anticipated sustained wind speed in Continental US is 150 mph. Using Bernoulli's equation calculate the associated stagnation pressure.

The concentration of toluene at the stack is 100 ppm and the polluted air is emitted at 100 m3/minute. The density of toluene is about 0.9 g/mL.   Pressure=1atm and temperature = 298K The stack height is 100m. The plume rise is 30 m. Estimate the down wind, centerline, ground-level concentration, at a down wind distance of 5000 meters from the stack. The atmospheric stability is class D, and the wind speed at a stack height is 5.0 m/s. ANSWER 0.54 ug/m3

Using Gaussian dispersion equations, the stability class, and dispersion coefficient data for a source emitting SO2 at a rate of 50 g/sec on a very sunny summer day with a wind speed at anemometer height of 2.9 m/sec, and effective stack height of 30 m at temperature = 293K, determine the stability class and dispersion coefficients for receptor distances of 200, 500, 800 m and 1000 m. Calculate and draw the ground level concentrations in ppbv as a function of distance (T=20 Celsius and P =1atm). The wind exponential coefficient = 0.2. ANSWER: Class B

Include the following test result and discussion:

The specific gravities and weight proportions for aggregates and bitumen at certain asphalt content are given in the table below, assuming the asphalt absorption is zero. Find the air voids, volume of the bitumen, voids in mineral aggregates, and the voids filled with asphalt. Weight of the sample in the water is 1470 gm.

Identify what the difference in volume is between effective precipitation and the volume under the hydrograph that is the response to that precipitation. Show how to calculate each.
