$2-2(10$ pts$)$ State regulations require a plant to have $30$ day supply of coagulant on hand when their

tanks are full. What height of a $3m$ diameter tank is required to meet the storage volume if the

average flow rate is $25$ million gallons per day $($MGD$)$ and the average coagulant dose is $16m\frac{g}{L}?$

Assume a coagulant specific gravity of $1\mathrm{.}335($alum$).$
