13-10 Consider a CSTR of volume 12 m3 operating at steady-state with a liquid feed rate of 0.3 m min-1. Suppose a relatively small amount of contaminant (0.06 m?) accidentally entered virtually all at once in the feed to the reactor. How many hours of production would be lost if the reactor continued to operate until the concentration of contaminant dropped to an allowable level of, say, 10 ppmv? (The lost production is due to the formation of off- specification product.)
