Civil and Environmental Engineering Question1. How is the problem of technology choice related to process selection and product design?
2. Suppose your boss has asked you to evaluate the possibilities of further office automation through linkage to the internet. How would you approach this problem? What information would you gather?
3. What is the main obstacle to using a manufacturing approach to the delivery of services?
4. Explain the differences between economies of scale and economies of scope.
5. Give three reasons why the flow of materials and the flow of control information should be analyzed together, at the same time.
6. What is meant by a sociotechnical approach to process analysis? Under what circumstances should such an approach be used?
To float a 160 pound man using helium balloons (assume 0.52 cubic feet per inflated balloon). How many balloons would it take? Assume density of air is 1.29 kg/cubic meter and the density of helium is 0.179 kg/cubic meter.
A CU triaxial test with σc = 20 psi is performed on a sand and a deviator stress of 80 psi fails the specimen. Previous tests revealed that the effective friction angle for this sand is 35°. Calculate the pore water pressure at failure.
A hawk flying at 2 m/s at an altitude of 45 m accidentally drops its prey. The parabolic trajectory of the falling prey is described by the equation below until it hits the ground, where y is its height above the ground and x is its horizontal dis..
Suppose that you issued a query against a search engine and the search engine retrieved 125 documents. Suppose that there are total, Define Data mining confusion matrix
A fluid flowing in a pipe 30cm in diameter has a uniform velocity of 4m/s. The pressure at the center of the pipe is 40KPa, and the elevation of the pipe's centerline above an assumed datum is 4.5m. Compute the total energy per unit weight of the ..
An engineering student is driving on a level roadway and sees a construction sign 180 m ahead in the middle of the roadway. The student strikes the sign at 56 kph. If the student was traveling at 90 kph when the sign was first spotted, what was th..
Find the time for one complete cycle of this motion if the spring constant is 21 N/m. (Assume that once the pendulum ball hits the spring there is no effect due to the vertical movement of the ball.)
For satisfactory operation, the static pressure at the pump inlet must not be lower than -6 m of water gage. Determine the smallest standard commercial pipe that will give the required performance.
Deflection of a Beam, If a beam of lenght L is fixed at the ends and loaded in the centre of the beam by a point load of F newtons the deflection
Presedimentation can reduce the suspended solids concentration of raw river water from 500 mg/L to 200 mg/L. How many pounds of dry solids does this represent per million gallons?
Determine the differential settlement between the centre line of the ring beam and under the centre of beam. The inner and outer radii of the ring beam are 8m and 12m respectively.
