3. Which of the following is NOT a knowledge area for project managers as specified in your text

A simply supported beam of 10m span carries a uniformly distributed load of 50kN/m spread over 5m from the left support and a 5kN concentrated load on its center . Its base is 250mm while deep is 500mm. Calculate the maximum deflection in mm. E = 2.0x10^5 N/mm2. Use the area moment method

A reverse osmosis membrane has a water permeation coefficient of 2 x 10-5 cm3/(cm2-sec-atm). It is used to treat a brackish water stream at 25 0C that contains 5,000 mg/L of salt (NaCl).

Question 1: Compute the osmotic pressure of the brackish feed stream

Question 2 – If the feed pressure is 27.2 Atm and the membrane area is 5 m2, what is the permeate flow rate.

How to model a stormwater management area from a real-world problem to a mathematical model?

What parties to the building design and construction process—in addition to architects, mechanical engineers, and electrical engineers—will play a substantive role in establishing the success of fire protection systems? For each party that is identified, briefly outline the role they can/should play.

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?
