1.Calculate all parameters and elevations at all even stations for vertical curve that has to passes through fixed point if PVI station is 8+00 and elevations is 5180.2. Fixed point station is 10+00 and elevation 5191.00, g1 = -6.6%, g2 = +5.4
2.For an element with a stress of 50 psi on the horizontal plane, 120 psi on the vertical plane, and 10 psi of shear stress that acts in the positive direction on the vertical plane and negative sense on the horizontal plane; draw the element below with correct orientation and senses. Draw the Mohr’s circle and find the principle stresses
Wastewater is discharged into an aquifer. This wastewater contains 0.1 ppm atrazine (a common herbicide). The MCL of atrazine is 5 ppb, the density is 1.19 g/mL and the solubility is 50 ppm. 500 ft away from the plant effluent there is a permeable..
An investor has invested $250,000 in a new rental property. Her estimated annual costas are $6,000 and annual revenues are $20,000. What rate of return per year will the investor make over a 30-year period ignoring the salvage value
A wastewater treatment plant must disinfect its effluent before discharging the waste water to a near-by stream. The wastewater contains 4.5x10^5 fecal coliform colony-forming units (CFU) per liter.
A steel cylinder initially contains nitrogen gas at 200kPa and 25oC. the cylinder is connected to a suply line containing nitrogen at 800kPa and 25oC. A valve is opened, allowing nitrogen to flow into the cylinder until the pressure reaches 800kPa. T..
A soil sample with a volume of 0.5 m3, dry unit weight = 18.1 kN/m3, water content = 5%, and Specific Gravity of the soil solids = 2.68. Calculate weight of water added to reach 90% saturation (in kilograms)?
Determine the design load for strength and serviceability limit states (short-term and long term), for a steel beam in a residential building with the following data;
If F_1=470N and theta=26 degrees, determine the magnitude of the resultant force of the three forces acting on ring A. Determine the direction of the resultant force measured counterclockwise from the positive x-axis.
how to design a simply supported rectangular concrete beam having cross section of 20 mm by 40 mm and a length of 3 meters that couldcarry a uniform load of 1000 KN
task - 1i- describe how test flumes and associated equipment are used to assess and confirm hydraulic behaviour in open
A distance of 1000 feet is to be taped in a manner to ensure a standard deviation smaller than ±0.06 feet. What must be the standard deviation per 100-ft tape length to achieve the desired precision?
The company makes no deposits during the subsequent 10 years. If the bank pays 10% interest, what is the amount in the account at the end of 20 years
Two different fluids flow over two identical flat plates with the same laminar free-stream velocity. Both fluids have the same viscosity, but one is twice as dense as the other. What is the relationship between the drag forces for these two plates
