Gigi works for a mineral processing company after graduation from PSU. One of the plants produces Portland cement at a rate of 5.1 metric tons per day. Their wet process dryer emits 12.9 kg/day of particles into the air after passing through an air pollution control system (APCS). The local Department of Environmental Protection (DEP) representative asks Gigi to estimate the removal efficiency of the air pollution control system. The problem is that Gigi does not know the rate of generation of the particles before going through the APCS. Fortunately, she took ME 433 at Penn State and remembers studying about emission factors. She quickly grabs the textbook and searches in the Appendices for an appropriate EF. Estimate the removal efficiency of this APCS as a percentage to three significant digits. Note: For consistency, use the EF tables provided in the Links portion of our course website, not some other website.\
