1. The mayor of Minneapolis (land area of 2,000 km2) foolishly decides to buy enough air punters ($250 each) to reduce the urban air pollution outdoors. Assume that 100% of the air pollution entering the air purifier is removed (i.e., the purifier is 100% efficient) and the airflow rate per hour is 0.018 m3/s. The average urban air pollution flow rate in Minneapolis was determined to be 5.5x10 mIs. How many of these air purifiers would the mayor need to purchase to reduce the urban air pollution by only 5%? How many tax payer dollars were spent in this effort?
