A tank contains 200 gal of fresh water. A solution containing 4 lb/gal of soluble
lawn fertilizer runs into the tank at the rate of 1 gal/min, and the mixture is
pumped out of the tank at the rate of 5 gal/min. Find the maximum amount of
fertilizer in the tank and the time required to reach the maximum.

Thumbi Irrigation Scheme in Mzimba district is under threat of flooding. In order to
mitigate against the problem, authorities have decided to construct a flood protection
bund (Dyke). Figure 1 is a cross section of a 300m long proposed dyke; together with its
foundation (key). Survey data for the proposed site of the dyke are presented in Table 1.
Table 2 provides swelling and shrinkage factors for the fill material that has been
proposed. The dyke dimensions that are given are for a compacted fill.
(1) Assume you are in the design office, use both the Simpson Rule and Trapezoidal
Rule to compute the total volume of earthworks required. (Assume both the dyke
and the key will use the same material).
(2) If you are a Contractor, how many days will it take to finish hauling the computed
earthworks using 3 tippers of 12m³ each? Make appropriate assumptions.
