Your company has been commissioned to design the water supply pipe network of 25 villa-style home units arranged in five buildings each containing five units on a steeply sloping side. The minimum available pressure at the main tapping is 35 m head, and the furthest fixture outlet is 7.5 m above the main (consider each row of buildings are 1.5 m higher than previous row adjacent to the street). The length of internal piping to the remote outlet in unit...

You have been asked, as a part of your college statistics course, to research the impact of clinical depression on an individual’s work performance. In 750-1000 words, you will be answering and researching the following questions: 1. Which type of method will you use to study this topic? Qualitative vs. Quantitative. 2. Who will be your chosen participants? What considerations must be undertaken in choosing your participants? 3. What sampling method will you use for your study? What considerations must...

You have been assigned the job of designing a rapid mix tank for a new water treatment plant. The design flow rate is 1.0 m3/sec. The average water temperature is 10 oC. The following design assumptions have been made: 1. Number of tanks = 1 (with 1 backup) 2. Tank configuration: Circular with liquid depth of 1.0m. 3. Detention time = 40 sec. 4. Velocity gradient = 750 s-1 Design the rapid mix by providing the following: a) Water power...

After you review the designs, describe which research design you would expect to find when searching for evidence relevant to your own research question from Week 2. Why? Explain your answer. The most common sampling method is the convenience sample; therefore, many of the studies that you find for evidence use this sampling method. What are the implications for using a convenience sample on the way you interpret and use the findings? Compare qualitative and quantitative research designs and outline...

Problem 7. Unit Analysis and Engineering Design You have been hired to analyze the university's water usage. Much of the water used on campus goes toward irrigation. The only athletic field at Angelo State that requires irrigation is the soccer field. The daily irrigation demand, D in gal/day, can be calculated as ET,x F,x Ax0.62 D- E Where D-demand in gal/day ETo-Evapotranspiration factor (0.23 in San Angelo) Fp= Plant factor (ranges from 0.3 to 1.0 depending on type of plants...

23. On your new job you have been asked to design a monitoring system for a water treatment process. You have chosen a dissolved-oxygen (DO) detector that operates at a frequency of 30 Hz. You have found that there is a significant source of noise at 5.0 kHz, with roughly the same amplitude as the measurement signal. You decide to minimize (90% reduction) the noise at this wavelength by building an RC filter. Diagram the signals in terms of amplitude...

suppose that you have been hired by the Florida state student health services department to design a case-control study to assess the following hypothesis among Florida state students at Florida State :Irregular sleep patterns increase the risk of headaches. Be sure that your design addresses the following elements: Refine the study hypothesis so that it is as specific as possible and contains all elements of a “good” hypothesis. How will you identify and define the cases? Are there any exclusion...
