The population from 1975 to 2015 are given below

1. Use the data given in the table to draw the population – time relation in X-Y graph
2. Use the Graphical extension Method to find the population in 2050
3. According to the plotted graph, use only one method (Geometric Increase method or Arithmetic Increase method) to find the population in 2050 (Explain why you select this method)
4. Use the estimated population in 2050 to design the main sewer pipe running 0.6 times full at maximum discharge. The water supplied from the water works to the town is at a rate of 200 LPCD. The manning’s n = 0.015 for the pipe material and permissible slope is 1 ‰. Variation of n with depth may be neglected. Check for minimum and maximum velocity assuming that the groundwater level is lower than the sewer pipe level.

Green building certification:

Your client is not convinced to go for any green building certification. She/he believes that buyers will not pay more for green buildings. He's asked for your opinion on this matter. What would your advice be?

You are the water supply manager for an organization that is contracted to supply water to a village with
population 3500 people. The water sources is a river and a pump is used to fill a 10000L tank. The turbidity
of the water is 4.1 NTU, therefore the manger has to determine the most appropriate amounts (mass) and
concentration of chlorine based water treatment chemical and the available chemical is HTH with 60%
chlorine
a) Work out how many grams of HTH you will require to add to one litre of water to a 1% chlorine
HTH solution.
b) You have four buckets, each containing 15 litres of water and added the following volumes of 1%
chlorine HTH solution.
1.0ml to bucket 1
1.5ml to bucket 2
2.5ml to bucket 3
4.0 ml to bucket 4
You wait for 30 minutes and measure the amount of residual chlorine that is in the water and get the
following results
0.0mg/l in bucket 1
0.13mg/l in bucket 2
0.35 mg/l in bucket 3
0.68 mg/l in bucket 4
Based on the Environmental Engineering judgement select the most appropriate chlorine dosage and
bucket and calculate the amount of 1% chorine HTH you will apply to the 10000L tank?
c. How much water will you treat per day if the water consumption is 90l/c/day and distribution losses
are 20%?
d. How much HTH in grams that must be applied in the 10000L tank per month?
e. Calculate the dosage in grams per minute of water purifying chemical, containing 20% (chlorine
based) active ingredients by mass, that will be required to treat a water supply system for a village
of 1500 people, given that water consumption per capita is 80L/day. The pumps and treatment
system are operated for 8 hours per day, required initial maximum chlorine concentration in treated
water at the plant is 4mg/L in the distribution network is 2mg/L. The water loses during distribution
are 15%.
f. After checking the chlorine levels in the village, one area out of 5 was found to have less than 2mg/L
of chlorine, what can you do to increase the chlorine levels for this particular area?

a) Determine the modulus of elasticity for a masonry prism made of 4 inc nominal clay brick having compressive strength of 8250 psi and type S mortar.

b) ) Determine the modulus of elasticity for a masonry prism made of Concrete masonry units compressive strength of 4050 psi and type N mortar.

c) What is modulus of rupture of masonry flexural tensile stress normal to bed joints in running bond with solid units and PCL type M mortar.

d) An engineer type of brick is used in two wythe wall with a standard CMU both laid in mortar bed joints in their stretcher position, mortar joint thickness is 3/8-in. Wall designed for composite action a)what is the allowable shear stress for a mortared collar joints according to MSJC code b) if it was grouted collar joints then what is the allowable shear stress according to MSJC code.

Cut Tape and Add Tape measure instruments are less desirable for accurate field survey usage primarily due to which of the following?

1. Explain workforce demographics and the key managerial skills for dealing with workforce diversity. What are two trends in workforce demographics?
2. What are the two main means of measuring personality? Discuss. please types the answers (don't use your handwritting. Thank you.

A 50 m3/s is conveyed down a 5-m wide rectangular channel (n = 0.012) with a slope
of 0.02 m/m. The channel transitions into a second channel with a slope of 0.0008 m/m. A
hydraulic jump occurs on the downstream channel. What is the downstream depth of the
second channel after the jump? What is the depth of the water before the jump? What is
the energy loss due to the jump? How long is the total distance of the hydraulic jump?

Prepare a comprehensive homework on polymer concretes and polymer impregnated concretes, their properties, standards and usage areas.

Does your organization produce a corporate or organizational sustainability report? If yes, locate the most recent report and review the initiatives documented there. Are there any initiatives of which you are unaware? If no report is presently produced, what initiatives within the organization would you recommend including in a future report?

2. A two-way 2 lane rural road (1 lane in each direction) has an estimated 1st year of design AADT of 15,000 vehicles. Given the following data, what is the design traffic loading in terms of ESA?     

Design period = 30 years; Annual growth rate = 3%; %HV = 15% NHAVG = 2.8 HVAG/HV; Average ESA/HVAG = 0.95

Your boss asks you to design a commercial-industrial building with planned column loads of 2,000 kN. For each of the locations described below, list the type(s) of foundations you would consider in preliminary planning. Briefly explain your choice.

1) Urban fill extending to depths of ~5 m, followed by ~50-60 m of a soft lacustrine fat clay deposit.

2) Peat to a depth of 2 m underlain by a thick dense granular deposit, the groundwater table is near the surface.

3) A thin (<0.5 m) layer of topsoil over a thick (~10 m) marine sand deposit over competent bedrock.

4) Variable glacial deposits to a depth of ~20 m. These deposits consist of smaller layers of dense granular deposits and overconsolidated fine-grained deposits with cobbles and present at developed locations in the area. Groundwater is variable with several perched aquifers.
