Problem: An eight lane urban freeway (four lanes in each direction) is on rolling terrain and has 11-ft lanes with a 4-ft right-side shoulder. The interchange density is 1.25 per mile. The base free-flow speed is 70 mi/hr. The directional peak-hour traffic volume is 5400 vehicles with 6% large trucks and 5% buses (no recreational vehicles). The traffic stream consists of regular users and the peak hour factor is 0.95. It has been decided that large trucks will be banned from the freeway during the peak hour. What will the freeway's density and level of service be before and after the ban? (Assume that the trucks are removed and all other traffic attributes are unchanged)
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.
Steam enters a turbine at 25 MPa, 550?C and exits at 5 MPa, 325?C at a flow rate of 70 kg/s. Determine the total power output of the turbine, its isentropic efficiency, and its second-law efficiency.
A horizontal cylindrical tank 4 ft in diameter and 10 ft long is full of water. Find the work done in pumping the water to a point 4 above the top of the tank.
If the steam is throttled down to 2 MPa before entering the turbine, find the actual turbine specific work. Find the change in exergy through the valve and the second-law efficiency of the turbine.
It is proposed to construct a new National Highway with four lane dual carriageway. The initial traffic in the year of completion construction i 1100CVPD.
A rig accelerates a load of 200000 lbf from zero to 60 ft/min in 5 seconds. compute the load shown on the hook load indicator.
At Point A, in a pipeline carrying water (γ=62.4 lb/ft^3) the diameter is 4.0 ft, the pressure is 10 psi, and the velocity 4 ft/s. At point B, 6ft higher than point A, the diameter is 2 ft and the pressure is 2ps
A simply supported beam is to span 15 feet. It will support a uniformly distributed load of 2 kips per linear foot over the full span and a concentrated load of 60 kips at midspan. Total deflection is not to exceed span/240.
nighttime traffic on a single lane of rural highway is light, with a flow of 40 vehicles/hour , and is well described by a Poisson arrival process. A racoon dashes across the road, without looking at a speed of 12 mph.
Design a circular radial-flow clarifier for a town with a projected population of 45,000. Assume that the wastewater flow is 400 L/capita-day. Size the system for a 2-hr
As a team, merge your findings into a team report and share your recommendations with your class.
If the design speed of a multilane highway is 60 mph, what is the minimum sight distance that should be provided on the road if (a) the road is horizontal and (b) the road has a maximum grade of 5%? Assume the perception/reaction time is 2.5 seconds...
