An intersection approach has three lanes, permitted left turns, and 6% left-turning volume with a through vehicle equivalent of 5.0 tvu/left turn. The saturation flow rate for through vehicles under prevailing conditions is 1,700 veh/hg/ln.
a. What is the left turn adjustment factor for the case described?
b. Determine the saturation flow rate and saturation headway for the approach, including the impact of left-turning vehicles.
c. If the approach in question has an effective green time of 45 seconds in a 75-second cycle, what is the capacity of the approach in veh/h?
The bent road has an E=200 GPa, G=75 GPa, and a radius of 30 mm. Use Castigliano's theorem and determine the vertical deflection at C. Include the effects of bending, shear, and torsional strain energy.
Crude oil flows through a level section of the Alaskan pipeline at a rate of 1.6 million barrels per day (1 barrels=42 US gallons) the pipe inside diameter is 48 inch and its roughness is equivalent to galvanized iron.
We have a situation where hydrogen gas at 300 degrees C is flowing out of a tube at the rate of 100 mL/min. The tube is located in a fume hood operating at 25 degrees C and 1 atm.
A 9,000-lb single wheel load is placed on a PCC slab that is 9.5 in. thick. The concrete has a modulus of elasticity of 5 million psi with a Poisson’s ratio of 0.15. The modulus of subgrade reaction is 225 pci. Tire pressure is 90 psi.
In an oedometer test, the void ratio of a clay sample changed from 1.62 to 1.41 as the vertical effective stress imposed on the sample was increased from 100 kPa to 200 kPa. Later on, the vertical effective stress on the sample was decreased
A streamlined, high-speed train travels at 200 km/hr. The flow over the train is similar to flow over a flat plate. Estimate the boundary layer thickness at the end of the train, which is 125 m long. The temperature is 10°C.
From the results of an oedometer test on an undisturbed sample of clay taken at a depth of 10 m from the ground surface, the maximum vertical preconsolidation pressure (s’vmax or s’c) was found to be 560 kPa. The clay layer has a saturated unit weigh..
An oedometer test on a clay soil gave the following results: Cc = 0.4, Ce = 0.08, OCR = 5. The thickness of the clay layer in the field is 2.6 m. The existing vertical effective stress at the mid-depth of the clay layer is 150 kPa. This vertical effe..
