Hi I need Stress Strain Graphs to be made for the following data tables. There should be 3 graphs, one for each table. I also need to know what material each sample is made of. I assume this is calculated from calculating the Modulus of Elasticity E. However I do not really know. I appreciate everything. The data tables are below this post.

Include the Following

  • Stress Strain graphs for each sample showing what variable and unit you have on both axes, and stating if it is sample 1, 2 or 3. Show the points in the graph and additionally a trendline.
  • Explain how you got your conclusion (i.e., show your work) including how it was calculated/how you got it, what value it had and what you compared with.
  • Your conclusion of what each of the three samples are made of.

For many years, snow removed from the campus roads and parking lots has been located to the field next to the river. The plowed snow has a relatively high salt content due to the application of road salt (NaCl) during the winter to keep the campus roads safe. NaCl quickly dissociates in water, resulting in sodium (Na+) and chloride (Cl-) ions. The US EPA recommends that the chloride content in remain below 230 mg/L to maintain healthy freshwater aquatic ecosystems.

Assume the following:

  • Chloride is a non-reactive pollutant
  • The Raquette River has a chloride concentration of 50 parts per million by mass

(note: 50 ppm chloride by mass = 50 grams chloride per 106 grams water; the density of water is 1 g/cm3, 103 cm3 = 1 L)

  • The Raquette River has an average flowrate of 1500 ft3/s
  • The runoff from the field has a chloride concentration of 5000 ppm by mass
  • The flowrate of the runoff from field during an average storm is 20 ft3/s
  • At the point of discharge from the field, the width of the river is 1000 ft, the depth is 5 ft, and there is near instantaneous mixing within 200 feet downstream of the field.
  1. Draw a mass balance diagram for this system.
  2. Calculate the chloride concentration of the river just downstream of the field one hour after an average rainstorm begins.
  3. Is your estimate for the chloride concentration in the river just downstream of the field above the EPA limit of 230 mg/L chloride? Show your calculations for the comparison.
  4. Name one fundamental assumption you needed to make to apply the mass balance approach to this problem. Is this a reasonable assumption? Briefly explain why or why not.

A certain city has a population equivalent to 123456 treatment plant which will serve the community until 2040

. a) Estimate the future population of this city in 2020 and 2040 using constant percent method if the rate constant is 0.0327 /year.

b) Determine the water and wastewater treatment plant design capacities for the period of 2020 to 2040. Use maximum (fmax) and minimum (fmin) factors of 2 and 0.5, respectively (Qmax = fmax Qavg and Qmin = fmin Qavg). Assume an average of 200 L/capita-day is the water consumption rate for the city in 2010 and 80% of the consumed water is collected as wastewater. What is the maximum hourly flow?

c) Determine the daily fire protection water requirement in 2020 and 2040?

d) Estimate the size of a tank for the water treatment plant that can store the raw water for 7 day. Take the depth as 3 m. What would be removal percentages of viruses (diameter = 50 nm) and bacteria (diameter = 1 μm) by this tank? Assume the specific gravity of each micro-organism is 1.05 and the water temperature is 20°

e) Estimate the size of equalization tank for the wastewater treatment plant that can hold the raw sewage for 4 hours. Take the depth as 3 m. What would be the size of the smallest particle size with specific gravity 2.0 that can be 100% removed by this tank? Assume that the water temperature is 20°C

PROBLEM 1:
A standard split-spoon penetration sampler is proposed for a geotechnical field exploration project. Calculate the area ratio of the sampler if its outside and cutting-edge diameter are 45 mm and 40 mm respectively
PROBLEM 2:
A soil sample has a mass of 2290 g and a volume of 0.00115 cu.m. After being completely dried in an oven, the mass of the sample is found to be 2035 g. If Gs=2.68, determine the air content in percent
PROBLEM 3:
A soil sample has a unit weight of 120 pcf and a degree of saturation of 65%. When its degree of saturation is increased to 80%, its unit weight increases to 124 pcf. Determine the saturated unit weight of the soil sample (lb/ft^3 ) if the unit weight of water is 62.35 lb/ft^3
