Ozone (O3) can be used to disinfect drinking water. Ozone is highly reactive and can react withchemical species and pathogens in water. It has been found in batch tests that ozone reactsaccording to a first-order reaction such that its concentration decreases by 50 percent in 10minutes (i.e., t1/2 = 10 min). A water supplier elects to use ozone as a pretreatment and injects itinto the water delivery pipe entering the plant. The pipe is 2.5 feet in diameter with a length of4,000 feet and handles a steady-state flow of 12,000 gpm. If the pipe can be considered a perfectPFR, identify the following.a. What is the water velocity in the pipe (in ft/s)?b. What initial concentration of ozone is required at the beginning of the pipe to have a 1.0mg/L concentration at the outlet?c. How much ozone must be added daily (in lb/day) if the O3 transfer process is 80% efficient?
