Suppose that the manufacturing company of Exercise 5.36 decides to change its acceptance scheme. Under the new scheme, an inspector takes 1 item at random, inspects it, and then replaces it in the box; a second inspector does likewise. Finally, a third inspector goes through the same procedure. The box is not shipped if any of the three inspectors find a defective. Answer the questions in Exercise 5.36 for this new plan
A city when its operation is normal uses a supply of drinking water
containing 15 mg /L of chloride (Cl-), but during periods of high water demand,
mixes with groundwater containing 65 mg/L Cl-. The two waters mix
completely in a 1400 m3 tank and then sent to the distribution system. the
demand for many days has been ~500 m3/d, and all the water has come from
the main supply. So, the demand increases to 700 m3 /d, and the additional
200 m3/d is extracted from the groundwater supply. How long can
continue with this operating strategy before the water entering the
distribution system contains ≥ 20 mg/L Cl-? (Note: chloride is not reactive).
