In a short-term laboratory test, the corrosion rate of nickel in boiling 10% phosphoric acid was observed to be 154 mils/year (1 mil = 0.001 in.). The density of nickel is 8.90 g/cm3 and its atomic weight is 58.7 g/mol.
(a) What is the mass loss per square centimeter after a 1 h immersion period?
(b) What is the corrosion current density in milliamperes per square centimeter?

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
