list and explain briefly five disposal technologies for hazardous waste

why, how and where project management can fit into the broadly defined area of environment sector. You may focus on specific environmental issues if you so wish. These may include but not be limited to, water quality, air quality, food protection, pollution abatement, remediation technologies, etc

A water tower supplies water to a city through a pipe with 1 ft diameter. The pipe is 0.5 miles long and is made of commercial steel pipe. Over the years, the supply line lost head and engineers are considering the replacement of 94 percent of the pipe length with a larger diameter pipe (same type). The peak water demand is 3.53 ft3/sec. How much pressure head could be gained by this strategy?

1. From a 2-hr test on a confined aquifer at 400 gpm, the following drawdowns were measured on a number of wells. Determine the transmissivity and storage coefficient using the Theis approach.

After reading the definition of aleatory and epistemic uncertainties, make a list of four uncertainties that you had to deal with that you would classify as primarily aleatory. Then do the same thing for four that are epistemic. At least some of these should be related to professional issues:

Your client has asked you to assist with a four storey steel frame building. Take ground floor as first floor. The frame is to be made of four columns line and three beam lines in the front elevation. Column height between floor to be 8m and the span of beam between columns is 9m. There are four bays of frames in the side elevation. Roof is made out of trusses. As part of your planning you are requested to prepare the following. a. Roughly Sketch the frame b. Indicate different loads you will consider and the combination of loads. c. Show the load path. Of the vertical and Horizontal load being carried from the roof to the soil d. Give examples of sub frames you will use to analyse elements to get values of B.M, S.F and Axial force. e. Discuss the method of analysis you will adapt and why? f. Kind of connections and bracing you will use and why? g. Discuss the steps you will take to meet the requirements as regard to Fire resistance, fatigue failure and corrosion protection. I need a better solution than the one in your site. Also please do not mention lacing and battern system. Can I please have clear answer with explanation ?

1. Lab Procedure

The cross-section dimensions of the 6061-T6 aluminum bar are 0.512 in x 0.248 in.

Attach the lead wires of the gages to the strain indicator as a quarter bridge circuit. (Note: the black and white lead wires are the common leads.)

Enter the gage factor (GF=2.11) into the strain indicator.

Record the specimen number (1, 2, or 3).

Balance the strain indicator and note the zero readings. Load the specimen according to the table below and record the strain values in the table below.

IMPORTANT: DO NOT EXCEED A MAXIMUM PRESURE OF 2500 lbs.

IMPORTANT: DO NOT EXCEED AXIAL FORCE OF 2500 lbs.

2. Lab Report

For each strain gage, construct a graph with load on the y-axis and net gage readings on the x -axis. Indicate if the gage readings are linear with force.

At each load level:

• Calculate Poisson’s ratio based on the strain readings
• Calculate the axial stress
• Calculate the modulus of elasticity based on the individual readings of axial stress and strain

Determine the average value of Poisson’s ratio and the modulus of elasticity. For 6061-T6, find accepted values of Poisson’s ratio, modulus of elasticity, and the yield stress.
