I want answers for part c pleasesubject is: Corrosion and Protection of Materials (a) It is known that structural design plays an important role in preventing corrosion. Hence,as an engineer, you have been assigned to design appropriate anti-corrosion structuresto solve the following hypothetical problems (1-4). Based on your corrosion knowledge,explain how such design is going to help solve the following problems.Problem 1: Design a chemical drainage tank that has a reservoir and an outlet toallow drainage when requiredProblem 2: A T-shaped pipe that directs two incoming water flow (A and B) to anoutlet (C) without causing cavitation damageProblem 3: Large water inlet (A) converges into a narrow pipe (B), design such astructure that will not cause cavitation damageProblem 4: Metal plate Y and Z are made of two different metals, design a structurethat will bind them together without causing galvanic/crevice corrosion(b) Given the following template (Figure 5), explain the differences between impressed-current cathodic protection (ICCP) and sacrificial anode technique by evaluating themin terms of the set-up and underlying principles. Determine what is X, Y and Z for bothsetups. Each setup should contain either an impressed current anode or a galvanic anode,a steel pipe, its protective current flow and the presence/absence of an extermal powersource. Kindly redraw TWO (2) of the following template in your answer booklet.SoilFigure 5 (c) Localised corrosion of metal pipes were observed in a seawater pumping plant. Thepipes were used to deliver seawater for cooling purposes to a thermal power plant. Thecooling seawater contained high concentration of chloride salts and an average pH of7.2. The surface of the interior surface of the pipes appeared to be uneven and filledwith pits. Based on your prediction of the type of corrosion that has occurred,recommend THREE (3) suitable solutions to prevent this corrosion from occurring andONE (1) best detection approach to probe the corrosion before it worsen.

Solution (c): Given Data: Average pH : 7.2
