This is a three part problem. This is the second part. A trapezoidal (m1= m2 = sqrt(3 )) channel is made of finished concrete. The channel slope is 30° below the horizontal, and the water flow rate is 5 cfs. Find the Froude number.

Concrete is a composite material. From microscopic point of view, it can be considered
as a three-phase composite with aggregate, cement paste and interface zone between
these two components.

1. For concrete with 28-day compressive strength of 35 Mpa (5076psi) made with
ordinary Portland cement and crushed granite aggregate, which phase of the
concrete is generally the weakest?
2. If the granite aggregate for the concrete mentioned in (i) is replaced by lightweight
aggregate. How would this affect the strength of concrete?
3. If we would like to increase the strength further, what approach shall we take?

Describe challenges and limitations in dealing with nanowaste. How can such issues be addressed and resolved?

Select the lightest W section to support a uniform distributed load WD=0.5 kip/ft,

W=1.4 kip/ft in addition to the section self weight.    The element will be simple

supported with a span of 24 ft. Use A36 (Deflection does not require to be verified).

why is zero traffic congestion wasteful? what social institutions prevent too much congestion and achieve optimal congestion? what is "optimal" congestion?

What do you (the students) see as your future engineering professional responsibilities in relation to preserving or protecting the environment?

1. Synthesis question: To simplify the presentation of air-quality data to the general public, many governments have created an air-quality index that summarizes with a simple number how clean or dirty the air is. For your national government (or for the USA if your own government doesn’t have one), search the web for info about the air-quality index. How is it defined in terms of concentrations of different pollutants? How do you interpret the index value in terms of visibility and/or health hazards?

You are to submit a final written report outlining the material introduced this 2020 summer semester. The typed report should be between 2 and 3 pages. The report should also include topics as outlined below:  

1. Introduction to Computers
2. Essential components of a computer
3. Computer ethics
4. Windows and Introduction to Office
5. Introduction to MS Word
6. Introduction to Excel
7. Introduction to Access
8. Introduction to PowerPoint

The final report will be worth 20% of your overall course grade and will serve as your final for this course this summer term. The report is due Wednesday, July 22, 2020 at 11:59 pm.

A 600’ long sewer pipe is being placed into a trench. Place the pipe at a gravity drainage slope of 2% towards station 6+00. The invert elevation at its beginning station (0+00) is 5395.00’. The pipe has an outside diameter of 1’ and a wall thickness of 1”.

a) Prepare an Excel table that lists the elevations for the top of the pipe for the stations 0+00, 1+00, 2+00, 3+00, 4+00, 5+00 and 6+00 *.

b) Calculate the invert elevation for the pipe at station 6+00. *

Note: Elevations for the top of the pipe are used to place leveling rods at those stations and control the depth of the pipe during construction (since the bottom of the pipe is then inaccessible).

Calculate the required parameters of a cipolleti earth channel in rough condition as per Lacey's theory to carry a discharge of 104 cfs with longitudinal slope of 1 ft/canal mile. Verify the designed parameters by using Kennedy’s formula. CLO-02.

it is requested to solve this within couple of hours as it's required urgently

Please explain as a Quality Engineer or Manager, how would you form a Team, what would you call it, what will their roles be, when would they get a chance to do their responsibilities and how would you enjoy the benefits?
