1. For an 18-inch pipeline designed for 150‚000 barrels per day‚ what is the short-run cost per barrel (per thousand miles) of transporting crude oil if the throughput is (a) 50‚000 barrels per day (b) 100‚000 barrels per day (c) 150‚000 barrels per day? Using chart 7‚ a) Cost of transporting 50‚000 barrels would be 30 cents. b) Cost of transporting 100‚000 barrels would be 17 cents. c) Cost of transporting 150‚000 barrels would 16 cents. 2.

Notes 6.1 Introduction Chapter - 6 LPG Bottling Plants Over 100 million LPG consumers in the domestic sector in India are serviced through a network of 9365 LPG distributors who are getting supply from 181 LPG bottling plants located across the country. In 2007-08‚ India consumed a total of about 1170 TMT of LPG which is around 10% of the consumption of total petroleum products in the country. Out of the total LPG consumption during the year 2007-08‚ almost 75% was used for cooking‚ 17% as

sodium hydroxide (NaOH) solution from a solid. Using a top-loading balance‚ ____ g of NaOH was transferred to a clean Erlenmeyer flask. Distilled water was then added until the solid was completely dissolved. The solution was transferred to a 250ml volumetric flask and mixed. Once mixed‚ the solution was bulked to the mark and mixed again. Finally‚ the solution was transferred to a clean plastic bottle and labeled. The second part was the preparation of ml 100ml of 3.0 M hydrochloric acid (HCl)

Background Knowledge of the dissolved oxygen (O2) concentration in seawater is often necessary in environmental and marine science. It may be used by physical oceanographers to study water masses in the ocean. It provides the marine biologist with a means of measuring primary production - particularly in laboratory cultures. For the marine chemist‚ it provides a measure of
