Question 50 - An aqueous solution with 2.5 g of a protein dissolved in 600 cubic centimeters of a solution at 20 degree Celsius was placed in a container that has a water-permeable membrane. Water permeated through the membrane until the h - level of the solution was 0.9 cm above the pure water. (a) Calculate the absolute temperature of the solution, T in Kelvin, where T (Kelvin) = T (degree Celsius) + 273.15. (b) Calculate the osmotic pressure, P of the solution by using the formula P = hrg where h is level of the solution, r is density of water with 1000 kg per cubic meter, g = 9.81 N / kg as gravitational acceleration. (c) Calculate the concentration of the protein solution, C in kg / cubic meter. (d) Calculate the molecular weight of the protein, (MW) = CRT / P where R = 8.314 Pa cubic meter / (mol K) as ideal gas constant.
1 2546Question 51 - A batch reactor is designed for the system of the irreversible, elementary liquid-phase hydration of butylene oxide that produces butylene glycol. At the reaction temperature T = 323 K, the reaction rate constant is k = 0.00083 L / (mol - min). The initial concentration of butylene oxide is 0.25 mol / L = Ca. The reaction is conducted using water as the solvent, so that water is in large excess. (a) Let the molecular weight of water is 18 g / mol and the mass of 1 kg in 1 L of water, calculate the molar density of water, Cb in the unit of mol / L. (b) Determine the final conversion, X of butylene oxide in the batch reactor after t = 45 min of reaction time. Use the formula X = 1 - 1 / exp [ kt (Cb) ] derived from material balance. (c) Find the equation of t as a function of X.
1 2946Question 62 – The names of the flow streams could be represented by : H1 for first hot stream, H2 for second hot stream, C1 for first cold stream, C2 for second cold stream. Data of supply temperature Ts in degree Celsius : 150 for H1, 170 for H2, 30 for C1, 30 for C2. Data of target temperature Tt in degree Celsius : 50 for H1, 169 for H2, 150 for C1, 40 for C2. Data of heat capacity Cp in kW / degree Celsius : 3 for H1, 360 for H2, 3 for C1, 30 for C2. (a) Find the enthalpy changes, dH for all streams of flow H1, H2, C1 and C2 in the unit of kW. Take note of the formula dH = (Cp) (Tt - Ts). (b) Match the hot streams H1 and H2 with the suitable cold streams C1 and C2 to achieve the maximum energy efficiency.

2 37434Question 68 – Biochemical Oxygen Demand (BOD) could be calculated using the formula BOD = (DOi - DOf) (Vb / Vs) where Vb = Volume of bottle in ml, Vs = Volume of sample in ml, DOi = Initial dissolved oxygen in mg / L, DOf = Final dissolved oxygen in mg / L. (a) By using a bottle of Vb = 300 ml with sample Vs = 30 ml, find the BOD if DOi = 8.8 mg / L and DOf = 5.9 mg / L. (b) By using a bottle Vb = 600 mL with sample Vs = 100 mL, find the BOD if DOi = 8.8 mg / L and DOf = 4.2 mg / L. (c) Find the average BOD = [ Answer of (a) Answer of (b) ] / 2. (d) If the BOD-5 test for (a) - (c) is run on a secondary effluent using a nitrification inhibitor, find the nitrogenous BOD (NBOD) = TBOD - CBOD. Let TBOD = 45 mg / L and CBOD = Answer of (c).
1 3151Question 69 - A well delivers 225 US-gallons per minute of water to a chemical plant during normal system operation. (a) Calculate its flowrate in the unit of mega US-gallon per day or MGD. (b) The following formula is written next to the chlorine feed point : (chlorine feed rate, lb / day) = (flowrate, MGD) X (dose, mg / L) x (8.34). If this formula is correct, then what should the chlorine feed rate to be in pounds per day (lb / day) if the desired dose is 2 mg / L. (c) Prove by calculations that the constant 8.34 in the formula next to the chlorine feed point is correct. Let 1 US-gallon = 3.78541 L and 1 mg = 0.0000022046 pound.

Perform the following tasks using MS-EXCEL: FUEL ESTIMATES COMPUTATIONS: This project is to compute the fuel needed for two types of airplanes, and the cost of the fuel. You must do all computations using formula, and do a chart. Use Page Setup to make the left margin 0.5 and the right margin 0.5 also. Put your name in the Title line, after "Fuel Estimates". Note the following: ? Col. D - H: You must enter correct formulas under Columns D through H (Flying Fuel, Reserve Fuel, Holding Fuel, Total Fuel Needed and Estimated Fuel Cost)!! Read and compute carefully! ? Cells C12, C13, C14, H13 or H14: When you use these cells in a formula, you must make them absolute cell references (F4 key after your type the cell reference, or enter the $ sign manually) ? Graph/Chart: Select cells A3:B8 (Plane and Flight). Hold down the "Control" key and select D3:D8. Hold down the "Control" key and select G3:G8. Create a chart (Insert- Chart, Finish) and position it in a pleasing way under the data for the flight. Print it on one sheet, in landscape mode. ? Print again, but with Formulae: There are two ways to show formulas: 1) Enter Control+` (the key with the ~ at the top left) or 2) Tools-Options, and under "Window Options" put a check mark beside "Formulas", then close the window.
If P is the population on the first day of the year, B is the birth rate, and D is the death rate, the estimated population at the end of the year is given by the formula: The population growth rate is given by the formula: B – D Write a program that prompts the user to enter the starting population, birth and death rates, and n, the number of years. The program should then calculate and print the estimated population after n years. Your program must have at least the following functions: 1. growthRate: This function takes its parameters the birth and death rates, and it returns the population growth rate. 2. estimatedPopulation: This function takes its parameters the current population, population growth rate, and n, the number of years. It returns the estimated population after n years Your program should not accept a negative birth rate, negative death rate, or a population less than 2. please answer my question ....

1 Tarot 1.1 Purpose - Tarot tool will duplicate the tarot-reading process for the user online. - Tarot is a craft that uses a deck of 78 cards to predict a user’s past, present and future. - The cards are picked by the user and arranged in a specific spread, which represents points in his past, present, and future; based on the meanings of the cards selected, interpretations are given. 1.2 Scope Only for registered user. 1.3 User Interface User Interface: 1. Question – This is only for user experience, and has no bearing on the formulae / process. Simple long text box. 2. Selection of field – radio button selection of 1 of 3 choices(Love, Career, Personal), which affects 1 of 3 card- meaning databases to be used. After selection, the unselected databases do not affect or interact with the system. 3. Spread Selection – radio button selection of 1 of 3 choices(Celtic Cross, Horse Shoe, Simple 3 Card). This determines the number of cards being picked and the specific spread database to be used. This also affects the specific report format being used, as well as the card- selection GUI. 4. Card Selection – based on the input 3, a specific layout is shown where the user needs to identify X number of cards (X also determined by input 3) which are then shown in the spread. Every card selection identifies the spread position constants (A, B, C, etc) with specific variable values (Card numbers) creating an array. Report format will display on a separate new page, in the following sequence – - Statement of question asked - Selection of field - Selection of spread - Detailed description of position data, positions identified as per spread selection - Card meaning as picked in field selection 1.4.5 Interfacing/Sourcing Details 1.4.5 Rules and Conditions - Data needs to be calculated for all fields, but only a maximum of 3 cards data should be shown in the free report. For the rest, a payment would be required. - Payment reports not in phase 1 - The report needs to be emailable (so functionality to convert to text file / html document should exist, which will then be emailed to the user’s email address).
