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…

Select all true statements. O To obtain a mining lease, the holder of a mining claim must absolutely acquire surface rights. | Mechanized stripping is used to expose the bedrock linearly to test the geological unit of interest on its full width, perpendicular to its contact with the surrounding units. The apparent length of a mineralized zone of interest is always shorter than its true width. Upon reaching commercial production, the purchaser of a mineral exploration property can pay a certain amount to the seller in exchange for a reduction of the percentage of the Net Smelter Return (NSR) retained by the seller.
A person is required to perform a lifting task. After conducting the analysis of the task shown below using the NIOSH lifting guidelines you determined that the task need to be redesigned to be acceptable. Unfortunately, the only factor that you can modify is the frequency of lifts per minute. What is the maximum number of lifts per minute that need to be used for this task so the NIOSH lifting guidelines are not exceeded? ANSWER: ________________
