Q1. Well water contained in an AISI 304 SS pipe network for chemical treatment and posterior distribution by aerial water pipes to different locations in a food manufacturing facility was analysed. The AISI 304 SS pipe network had an approximate 300 m length, 154 mm diameter and 2.0 mm wall thickness. The AISI 304 SS pipes were welded using a Tungsten Inert Gas (TIG) welding procedure. In-situ weld quality assurance was tested by pressurized WW, and no pinhole leakage was detected. After the pipe network remained out of service for 6 months at room temperature containing stagnant, pressurized well water, pitting corrosion was observed on the weld joints and the base material by the presence of multiple pinhole leaks.(a) Discuss, with chemical equations if relevant, TWO corrosion events that may have caused the pitting corrosion.(b) What practical steps could have been taken to mitigate for this potential outcome?(c) Identify corrosion inhibition methods to mitigate for the corrosion…

After the sinking of RMS Titanic, US operated the International Ice patrol with the purpose of monitoring the presence and movements of icebergs in the Atlantic and Arctic oceans. Once, they observed a unique tabular iceberg in a form of a rectangle (250 km x 50 km x 300 m). How many years would it take to melt the iceberg solely by heat from the sun if the ice absorbs a mean of 98 J/m2 -s, 12.5 hrs per day? Note: the exposed area for heating is 250 km x 50 km and the density is 920 kg/m3 . This is my solution.
