Assuming there is a $20\mathrm{.}6$ X $104$ L of water produced per acre by a $2"$ rainfall event and we measured $98\%$ runoff from the concrete surface at $20$ degree slope. How much total runoff would you expect from $1$ acre of concrete surface with a $20$ degree slope? $($see question #$5$ in the lab handout$).($hint: there could be more than one correct answer$)$

$4120$ liters

$201880$ liters

$20\mathrm{.}2$ X $10000$ liters

$185400$ liters
