carbon make up only a small percentage of the carbon in the universe‚ the average of the masses of all carbon atoms is slightly higher than 12‚ so the atomic mass for carbon is actually 12.011. Objective Analyze the isotopes of “Metallo” and to calculate its atomic mass Materials sample of metallo (bag of mixed nuts‚ bolts‚ and washers) balance Procedures Obtain a sample of the new element “Metallo.” Separate the three isotopes of Metallo (nuts‚ washers‚ bolts) and measure the mass of each isotope

Question 1: The productivity index for a well in an undersaturated reservoir is 2.6 bbl/d/psi. Calculate the drawdown required for a production rate of 800 bbl/d of oil with an average reservoir pressure of 2500psi. Question 2: A reservoir has been producing under stabilized flow condition at 1200 bbl/d with a flowing bottomhole pressure of 1800psi. The average reservoir pressure is 3000psi. Calculate the productivity index. Assume the wells being produced above the bubble point pressure. Question

4: Feb 2- 6‚ 2009 1. Consider a gas that occupies 1.00 dm3 at a pressure of 2.00 bar. If the gas is compressed isothermally at constant external pressure‚ Pext‚ so that the final volume is 0.500 dm3‚ what is the smallest value Pext can have? Calculate the work involved using this value of Pext. Solution For compression to occur‚ the value of Pext must be at least as large as the final pressure of the gas. P1 = 2.00 bar‚ V1 = 1.00 dm3‚ V2 = 0.500 dm3‚ P2 = ? = 4.00 bar This is the smallest

)]*rd * (1-t) Where WACC= Weighted Average Cost of Capital re = cost of equity rd = cost of debt E = market value of equity D = Market value of debt t = tax rate 2. Calculate cost of equity using the Capital Asset Pricing Model (CAPM). Given are the values: Rf = 5.74% β = 0.8 Rm – rf = 5.9% Required to calculate the cost of equity re; using CAPM. It follows that from our formula Re = rf + β (Rm –rf) = 5.74% + 0.8 (5.9%) = 10.46% Assumptions: We decided to use the 20 year treasury

forma operating statement we used ratios of COGS/Sales and Operating Expense/Sales for years 2004‚ 2005‚ and 2006. We then took the average of these ratios and multiplied them by sales for 2007 to come up with 2007 COGS and Operating Expenses. To calculate interest expense we included the outstanding loan Jones has with Verden and the new line of credit he would be taking out with Southern Bank and Trust. We calculated Verden’s interest expense by multiplying the rate of 8% by the outstanding amount

INTRODUCTION Parts Emporium‚ Inc. is a wholesale distributor of automobile parts formed by two disenchanted auto mechanics‚ Dan Block and Ed Spriggs. Originally located in Block’s garage‚ the firm showed slow but steady growth for 7 years before it relocated to an old‚ abandoned meat-packing warehouse on Chicago’s South Side. With increased space for inventory storage‚ the company was able to begin offering an expanded line of auto parts. Fifteen years later‚ Parts Emporium was the largest
