Question 79 - (a) The American Petroleum Institute gravity, or API gravity, is a measure of how heavy or light a petroleum liquid is compared to water. Let SG = specific gravity of petroleum liquid, and V = barrels of crude oil per metric ton. Given the formula for API gravity = 141.5 / SG - 131.5 and V = (API gravity + 131.5) / (141.5 x 0.159), find the relationship of SG as a function of V. (b) An oil barrel is about 159 litres. If a cylinder with diameter d = 50 cm and height h = 50 cm is used to contain the oil, find the volume V of the cylinder in the unit of oil barrel by using the formula V = 3.142 x d x h x d / 4. (c) First reference : 1 cubic metre = 6.2898 oil barrels. Second reference : 1 cubic metre = 6.37 oil barrels. What are the 2 factors that cause the difference in such reference data?
1 3023MASS TRANSFER - EXAMPLE 4.3 : According to Adolf Eugen Fick (1829 - 1901) : rate of diffusion v increases with less wall thickness t, increased area A and decreased molecular weight of a fluid M. The diffusion constant D decreased with increasing M. (a) By assuming v, t, dP, A, M and D changes proportionally of each other, find the equation of v as a function of t, dP, A and D. (b) The ratio of self diffusion constant D, at T = 273 K and P = 0.1 MPa, for gases B and C are 1.604 : 0.155. If only 2 gases exist in such a system : hydrogen and nitrogen, find the type of gas for B and C with reference to their molecular weights M. (c) By using the equation of kinetic energy 0.5 MV = constant where V = square of v, find the ratio of V for B and V for C, or V(B) / V(C), as a function of M(B) and M(C), where M(B) is molecular weight of B and M(C) the molecular weight of C : Graham's Law of Diffusion.
1 2404Question 88 - In the calculation of the growth of bacteria, colony forming unit (CFU) in serial dilution is used. In a laboratory, viable count assay is used to estimate CFU. Formula applied is CFU / mL = (number of colonies x dilution) / (amount plated, in unit mL). Acceptable plate count is either between 20 and 200 or between 30 and 300 according to 2 different references. A wastewater sample of 200 ml is added to and mixed with 1.8 L of sterile water. Another 200 ml of the mixture is added to and mixed with 1.8 L of sterile water. (a) Calculate the dilution of first mixture and the dilution of the second mixture. (b) 100 microlitres of wastewater samples from the first mixture and the second mixture are placed separately on 2 different alga plates. The first plate has 250 colonies and the second plate has 23 colonies. Calculate the average CFU / mL.

1616Question 95 - The following formula is used as a reference : (analyte signal) / (internal standard signal) = (f-factor) x (concentration of analyte) / (concentration of internal standard). A solution containing 3 mM of analyte and 4 mM of internal standard gave peak signals of 2 and 3 mamps respectively. Another similar solution containing 2 mM of analyte and 1 mM of internal standard gave peak signals of 1 and 4 mamps respectively. Find the average f-factor.

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.
