Two straight sections of freeway cross at a right angle. At the point of crossing, the east-west highway is at elevation 150 ft and is a constant +5.0% grade (upgrade in the east direction), the north-south highway is at elevation 125 ft and is a constant -3.0% grade (downgrade in the north direction). Design a 90-degree ramp that connects the northbound direction of travel to the eastbound direction of travel. Design the ramp for the highest design speed (to the nearest 5 mph) without exceeding a minimum D of 8.0. (Assume the PC of the horizontal curve is at station 15+00, and the vertical curve PVIs are at the PC and PT of the horizontal curve). Maximum allowed superelevation by design standards is 12%.Determine the following:Stationing and elevations of the horizontal curve PC and PTHorizontal curve radius and lengthStationing and elevations of the vertical curve PVCs and PVTsVertical curve lengthsLength of constant grade in between the 2 vertical curves (if any)
A rinsed and dried filter weighed 0.3588 grams before the sample was filtered and then weighed 0.3630 grams after the sample was filtered and being at dried at 103C. What is the TSS for this sample
Consider a metal single crystal oriented such that the normal to the slip plane and the slip direction are at angles of 42.1* and 48.9*, respectively, with the tensile axis.
a ball is thrown with a valocity of 30 m/s at an angle of 40 degrees above the horizontal from the top of a 100m tall building. what is balls velocity when it lands. (neglect air resistance in both cases) DO NOT USE 2D projectile motions, only work ..
A four year financial project has net cash flows of $20,000; $25,000; $30,000; and $50,000 in the next four years. It will cost $75,000 to implement the project. If required rate of return is 20%, conduct a discounted cashflow calculation
A CMFR is to be designed to remove contaminant A from water with a steady-state efficiency of 95 percent. The decay reaction is zeroth order, with a rate constant of 0.1M/h. The inlet concentration of A is 0.5 M.
The river flow at an upstream gauging station is measured to be 1500 m3/s, and at another gauging station 3 km downstream, the discharge is measured to be 750 m3/s at the same instant of time.
a water main is used to refill an elevated storage tank during the night. a 100 ft long, 12 in steel pipe (ks=.06 mm) connects to the booster pump that provides a pressure of 75 psig at the pump outlet
Suppose that in an apparatus it is necessary to maintain precisely the cross section of a 20mm circular nickel steel bar. If this bar is heated to 200 deg Celcius, what tensile force should be applied to the bar to maintain its cross sectional dim..
what is the force P to move the cabinet if a) caster A and B are locked b) B is locked A is free to move c) A is locked B is free to move p is applied from the left side pushing right. the width of the cabinet from caster a to b is 24 inches.
For an elevated storage tank , if the minimum allowable pressure = 300 kPa, Height of pipe system at low-pressure service location = 6 m, and head loss from tank to service location: average daily conditions = 11 m
Congress banned the production of the speedy dry cleaning company's dry cleaning fluid in 2000. Speedy is using a new cleaning fluid. The new dry cleaning fluid has one-sixth the volatility of the former dry cleaning fluid.
A bridge has been constructed between the mainland and an island.The total cost (excluding tolls) to travel across the bridge isexpressed as C = 50 + 0.5V, where V is the number of veh/h and C isthe cost/vehicle in cents.
