    Concept of ATC Loss Calculation (By Jayant Sinha‚ DGM (IT)) In absence of feeder metering in the past‚ substantial portion of T&D loss‚ including theft of electricity was attributed to agricultural consumption. While‚ agricultural consumption was around 20-25%‚ utilities were showing it as 35-40% and correspondingly T&D losses were shown as 20-25%. Also‚ T&D loss was being computed by showing electricity bills issued to consumers as accrued income‚ and not on the basis of actual collection. Therefore

    Quantitative Analysis of a Soluble Sulfate Steven English Lab Instructor: Dr. Campo Date: Tuesday‚ February 5th 2013 Pre-Lab Questions A. Adding the acid to the sodium sulfate solution results in an increase in the solubility of any free anions present in the sample. This will happen because the present anions will bind with the hydrogen cations present in the acid. B. The sodium sulfate is boiled because experiments have shown that barium sulfate is 50 times more soluble at 100°C

    Calculation of Allele and Genotype Frequencies & Hardy-Weinberg Equilibrium Theory INTRODUCTION Population geneticists study frequencies of genotypes and alleles within populations rather than the ratios of phenotypes that Mendelian geneticists use. By comparing these frequencies with those predicted by null models that assume no evolutionary mechanisms are acting within populations‚ they draw conclusions regarding the evolutionary forces in operation. In a constant environment‚ genes will continue

    Thermochemistry: An Ice Calorimeter Determination of Reaction Enthalpy Shannon Wedepohl 9/17/13 Abstract: During this experiment‚ an ice calorimeter was used to measure the change in volume in milliliters of magnesium metal and 1.00 M of sulfuric acid. We found the experimental molar enthalpy of the reaction to be ∆H = -370 ± 1 kJ/mol at 0˚C. This compares with an expected value of -466.9 kJ/mol at 25 ˚C‚ a 20.75% difference. Introduction: Many chemical reactions truly only

    measurements {∑Pf1+Pf2+Pf3+…Pfn}/n. According to teachings on this subject this is entirely incorrect. Furthermore a document was written about this very theory some years ago by one Mr. Lampkin and it is apparent that no change was made to correct the calculations (please refer to). The following is a review of the general theory. Power factor (Pf) is the ratio of real power (kW) to the apparent power (kVA). Power factor decreases with the installation of non-resistive loads‚ such as motors‚ transformers

    Cash Flows for Discounting Calculations When managers are forecasting the cash flows for a project‚ they will consider the expected revenues and costs‚ but they must also include an estimate for working capital requirements. The working capital will be required in period 1 to allow the business to acquire inventories and build up debtors (receivables) to the extent that these are not matched by trade. The working capital will be recovered at the end of the project when the inventories are sold‚

    Sample Real GDP Calculation Econ 102-1 Alley Nominal GDP is calculated by summing the value of goods and services produced in a given year using the prices of these outputs in that year. If the general price level increases or decreases from one year to the next‚ it is difficult to compare the amount of output that a country produces across different years. To correct for this‚ we want to value output in every year using the same prices. In other words‚ we calculate real GDP. Consider the

    This experiment will test the suggestion that the enthalpy change between a metal and a solution of a salt is related to the relative position of the two metals in the reactivity. Presumably the further apart in the series the bigger the enthalpy change will be. The experiment is as follows‚ 1) Zn(s) + CuSO4(aq) ZnSO4(aq) + Cu(s) 2) Zn(s) + Pb(NO3)2(aq) Zn(NO3)2 (aq) + Pb(s) Both of the solutions will be in 1mol.dm-3 Apparatus: Distilled Water Polystyrene Cup
