Given the following geometry of an intersection: Four lanes fornorth and southbound traffic; two lanes for east and west boundtraffic. The peak hour volume for: north bound traffic is 1400vehicles with 10% left and right turns, southbound traffic is 1100vehicles with 10% lefts and rights; East bound traffic is 550 vehicles with 15% lefts and rights; westbound traffic is 300vehicles with 15% lefts and rights.
a) What is the ratio of demand for time with respect for timeavailable?
b)If you add left turn lanes for north and southbound traffic, whatis the ratio of demand for time with respect to time available?
c) What is the demand for time if left turns are provided for allapproaches?
the block w shown in figure below has a mass of 250 kg. bar ab rests against a smooth verticalnbspwall at end b and is
The operating cost will be $10,000 per quarter with a salvage value of $25,000 after its 2-year life. Process B will have a first cost of $250,000, an operating cost of $15,000 per quarter and a $40,000 salvage value after its 4-year life.
Discuss and use examples to explain the specific factors that you will need to consider when pricing the following items in the bill of quantities foundation excavation
The dry density of a compacted sand is 1.87 Mg/m^3 and the density of the solids is 2.67 Mg/m^3. What is the water content of the material when saturated. Include a phase diagram.
What is the reaction that occurs with hexanal and propanol (give both the hemiacetal and acetal products)?
Determine what fair amount she should receive if she decides she want to be paid: a. In 2 equal installments - one immediately (at T=0) and one at the end of month 36.
Two parallel plates are separate at a distance of 2mm by a fluid. If a shearing stress of 150 Pa is developed at the upper plate when it is pulled at a velocity of 1m/s. Determine the viscosity of the fluid.
THe 50 kg crate is stationary when the force P is applied. Determine the resulting acceleration of the crate if (a) P=0, (b) P=150 N, and (c) P=300 N
A Proctor compaction test in the laboratory on a borrow pit soil gives a maximum dry unit weight of 19 kN/m3 and optimum water content of 11.5%. The bulk unit weight and water content of the soil in the borrow pit are 17.2 kN/m3
Knowing that the magnitude of P is 35 N, determine by trigonometry (a) the required angle a if the resultant R of the two forces applied to the support is to be horizontal, (b) the corresponding magnitude of R.
Water flows through a 200 m long ,30 cm diameter steel pipe with surface roughness 0.046 mm at a rate of 0.25 m^3/s .Find the pressure(P2)considering both friction and minor losses
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
