The scenario provides a situation where two pH meters used to monitor a process do not agree. The measurement is critical. Students work as a team to solve the problem as quickly and inexpensively as possible.
All data is provided in the form of process control charts.
Back to top list. NMP works as quickly as methylene chloride on alkyd paints, but is slower on polyurethane-painted surfaces. Because graffiti is usually written using alkyd spray paints, NMP can be used to strip off graffiti and then removed quickly enough to avoid destroying a polyurethane coating beneath the graffiti.
