Extracted text: ii. Illustrate the flow of current and identify the location of the anode and cathode. You may directly sketch out rough locations of A – F on your answer booklet and illustrate the flow of current between the alphabets with arrows. (b) In the oil exploitation process, a pumpjack shown in Figure 4 is used to mechanically lift oil out of the oil well. It does that via a prime mover which supplies rotational energy to the crank and results in the cyclic pumping movement of the horse head. Over a period of time, one specific type of corrosion occurred. Horse Head Prime Mover Crank Figure 4 Using labelled diagrams, demonstrate the mechanisms for the type of corrosion that has occurred. Do state the type of corrosion in your explanation. (c) Given that Brand X's customised drilling fluid is low in CO2 content, high in solid content, low solution pH, used at room temperature and does have deoxidiser and sulfur removal agent. Discuss the impact of such customised specifications by relating it to its property (corrosiveness).
