Consider two alternative water resource projects, A and B. Project A will cost $2,533,000 and will return $1,000,000 at the end of 5 years and $4,000,000 at the end of 10 years. Project B will cost $4,000,000 and will return $2,000,000 at the end of 5 and 15 years, and another $3,000,000 at the end of 10 years. Project A has a life of 10 years, and B has a life of 15 years. Assuming an interest rate of 0.1 (10%) per year.
Describe the crystalline or atomic structure of the following minerals: 1) Brucite 2) Gibbsite 3) Bentonite 4) Illite
The block is acted by its weight W=200 lb, a horizontal force Q=600 lb, and the pressure P exerted by the inclined plane. The resultant R of these forces is up and parallel to the inclined thereby sliding the block up it. Determine P and R.
We would continue embankment work even if winter season and my question is what is swelling amount of compacted soil for 30cm thickness and 95% compaction degree by freezing.
