Conversion factors:

$1$ barrel $=55$ gallons, $1$ kilogram $=2\mathrm{.}2$ pounds, $1$ gallon $=3\mathrm{.}79$ liters, $1$ liter $=1,000$ centimeter ${?}^3,$

$1$ kilogram $=1,000$ grams, $1\mathrm{.}0m^3=264$ gallons, $10,000m^2=1\mathrm{.}0Ha$

Problems $($please list all assumptions that you use in solving each problem$)$:

A sanitary $($solid waste$)$ landfill has available space of $16\mathrm{.}2$ Ha at an average depth of $10$ m $.$ Seven hundred sixty$-$five $(765)$ cubic meters of solids waste per day are dumped at the site five days a week. The waste is compacted to twice its delivered density. Draw a mass balance diagram and estimate the expected life of the landfill in years. Assume the landfill operates $5$ days$/$week for $52$ weeks$/$year$.$

HINTS: To determine the expected life of the landfill, find the available space and the annual $($accumulation$)$ volume of compacted solid waste.
