## Calculating Adiabatic Cooling Look at the topographic Profile below and calculate the temperature at the top of the mountain. Assume that the air parcel is forced to rise up and over an 8,000-foot elevation mountain. The initial temperature is 65.5°F at sea level on the Windward (west) side of the mountain. Assume that the Lifting Condensation Level (LCL) is at 3,000 feet elevation where the Dew Point occurs. The Adiabatic Lapse Rate is 3.6°F = 1,000ft in elevation. To simplify, round down to 3°F. Find the difference in elevation from sea level and final elevation. Multiply lapse rate by feet in thousands. (3° x 8”) = 24° F Next, subtract difference in temperature (24°) from sea level temperature to get your apex temperature. (65.5°-24°) = 41.5° F Temperature on top of mountain is 41.5°F Now you try it! * Note: The calculation produces an approximate ambient temperature. Seasonal, diurnal, and other variations should also be considered. 78º 96º 6,000ʼ 9,000ʼʼ ______ º F ______ º F

## VAC3042 Assignment 2 Dual-pipe water supply system 2015 Preamble: In the interests of a sustainable future a regional water agency, in conjunction with a private sector investor, intends to develop a new urban release area to house over 12000 people. Your consultancy firm of hydraulic engineering designers has been given the task of performing a preliminary engineering design of a sustainable dual-pipe water supply system, including a potable water treatment plant, to serve this residential development. Design/Project Brief: The ‘Client’ requires a preliminary design for a dual-pipe water supply distribution system and a potable water treatment plant to serve 3500 equivalent tenements (ET) in a proposed new residential development. The design of the distribution pipes, service storages and pumps is to be based on the typical maximum day demand patterns given in the HE Lecture Notes, the schematic diagram and the additional data provided below. The potable water (PW) supply is to be gravity fed from a water treatment plant (WTP) at T as supply from reservoir R is of poor quality (i.e. turbidity 10-15 NTU, true colour 15-30 HU, and minor taste and odour problems). Wastewater from the residential development will be piped to the wastewater treatment plant, (WWTP) labeled A, using a SewerPlex NuSewer reticulation system (not shown), where it will be treated to provide reclaimed water to Class A standard. The Class A non-drinking water (NDW) supply is to be used for toilet flushing, car washing and garden watering and will be a boosted system fed from a 12ML reclaimed water store located in the WWTP. R P/S POS High Level Zone T 1500 ET E J F (RL74m) K (RL74m) Pipe lengths: TJ = 8.80km JL = 4.07km JK = 1.46km EF = 1.50km P/S C (RL66m) Freeway Low Level Zone POS 2000 ET L M (RL54m) D (RL54m) P/S B Pipe lengths: AB = 6.43km LM = 1.39km POS BD = 1.59km BE = 3.96km A Not to Scale All distribution pipes to be 5mm spiral welded steel pipe with cement lining (Use data sheet provided). Base (or ground) levels for tanks and operational water levels (OWL) for storages: Tank B Base level = 85.3m Tank E Base level = 118.1m Tank J Base level = 117.3m Tank L Base level = 89.3m WWTP storage at A Minimum OWL = RL30m, maximum OWL = RL32m WTP storage at T Minimum OWL = RL135m, maximum OWL = RL137m Other conditions and design criteria: Average occupancy rate = 3.5 persons per household Minimum residual head at entrance to water supply reticulation systems is to be 25m Assume all on-ground service storage tanks are 16m in diameter Allow 0.7m for the unusable dead volume and 0.6m clearance from FSL to top of each tank Fire flow of 20 L/s for 4 hours duration is to be taken from PW supply Pumps at A and C are to operate from 3am to 9pm on days of maximum demand The pump station at C is at RL66m and is midway between B and E. The profile of pipeline BE is concave with the low point at C Allow 6 hours breakdown volume in the NDW system Allow 12 hours breakdown volume in the PW system Assume an efficiency of 75% for pumps Ignore minor system losses and any waterhammer effects Design of the tank top-up pumps is not required Use the Hazen-Williams design chart for pipe sizing and assume C = 120 Assume the available daily NDW recycled flow from the NuSewer system to be 80% of the sanitary flow rate (SF) to the WWTP Detention times: Raw water storage (6 hours), clear water/chlorine contact storage (9 hours) Clarifier design criteria: detention time 1.8 hours, maximum surface loading rate 72 m/d, inlet pipe 2m diameter, 60° side wall slope, tank base 7.1m2, other guidelines from lecture notes Filter design criteria: multi-media filters, normal filtration rate 6 m/hr, maximum filtration rate when one filter is being backwashed 10 m/hr, other guidelines from lecture notes There is no design required for the PW, NDW and sewer reticulation systems.

## Question 1 In order to properly manage expenses, the company investigates the amount of money spent by its sales office. The below numbers are related to six randomly selected receipts provided by the staff. $147 $124 $93 $158 $164 $171 a) Calculate ̅ , s2 and s for the expense data. b) Assume that the distribution of expenses is approximately normally distributed. Calculate estimates of tolerance intervals containing 68.26 percent, 95.44 percent, and 99.73 percent of all expenses by the sales office. c) If a member of the sales office submits a receipt with the amount of $190, should this expense be considered unusually high? Explain your answer. d) Compute and interpret the z-score for each of the six expenses. Question 2 A survey presents the results of a concept study for the taste of new food. Three hundred consumers between 18 and 49 years old were randomly selected. After sampling the new cuisine, each was asked to rate the quality of food. The rating was made on a scale from 1 to 5, with 5 representing “extremely agree with the quality” and with 1 representing “not at all agree with the new food.” The results obtained are given in Table 1. Estimate the probability that a randomly selected 18- to 49-year-old consumer a) Would give the phrase a rating of 4. b) Would give the phrase a rating of 3 or higher. c) Is in the 18–26 age group; the 27–35 age group; the 36–49 age group. d) Is a male who gives the phrase a rating of 5. e) Is a 36- to 49-year-old who gives the phrase a rating of 2. f) Estimate the probability that a randomly selected 18- to 49-year-old consumer is a 27- to 49-year-old who gives the phrase a rating of 3. g) Estimate the probability that a randomly selected 18- to 49-year-old consumer would 1) give the phrase a rating of 2 or 4 given that the consumer is male; 2) give the phrase a rating of 4 or 5 given that the consumer is female. Based on the results of parts 1 and 2, is the appeal of the phrase among males much different from the appeal of the phrase among females? Explain. h) Give the phrase a rating of 4 or 5, 1) given that the consumer is in the 18–26 age group; 2) given that the consumer is in the 27–35 age group; 3) given that the consumer is in the 36–49 age group. Table 1. Gender Age Group Rating Total Male Female 18-26 27-35 36-49 Extremely Appealing (5) 151 68 83 48 66 37 (4) 91 51 40 36 36 19 (3) 36 21 15 9 12 15 (2) 13 7 6 4 6 3 Not at all appealing(1) 9 3 6 4 3 2 Question 3 Based on the reports provided by the brokers, it is concluded that the annual returns on common stocks are approximately normally distributed with a mean of 17.8 percent and a standard deviation of 29.3 percent. On the other hand, the company reports that the annual returns on tax-free municipal bonds are approximately normally distributed with a mean return of 4.7 percent and a standard deviation of 10.2 percent. Find the probability that a randomly selected a) Common stock will give a positive yearly return. b) Tax-free municipal bond will give a positive yearly return. c) Common stock will give more than a 13 percent return. d) Tax-free municipal bond will give more than a 11.5 percent return. e) Common stock will give a loss of at least 7 percent. f) Tax-free municipal bond will give a loss of at least 10 percent. Question 4 Based on a sample of 176 workers, it is estimated that the mean amount of paid time lost during a three-month period was 1.4 days per employee with a standard deviation of 1.3 days. It is also estimated that the mean amount of unpaid time lost during a three-month period was 1.0 day per employee with a standard deviation of 1.8 days. We randomly select a sample of 100 workers. a) What is the probability that the average amount of paid time lost during a three-month period for the 100 blue-collar workers will exceed 1.5 days? Assume σ equals 1.3 days. b) What is the probability that the average amount of unpaid time lost during a three-month period for the 100 workers will exceed 1.5 days? Assume σ equals 1.8 days. c) A sample of 100 workers is randomly selected. Suppose the sample mean amount of unpaid time lost during a three-month period actually exceeds 1.5 days. Would it be reasonable to conclude that the mean amount of unpaid time lost has increased above the previously estimated 1.0 day? Explain. Assume σ still equals 1.8 days.
