Determine the peak flow using the rational method from $2$ years$-$storm for the drainage basin $(55$ acres in New Jersey$)$ having a runoff coefficient of $0\mathrm{.}35$ and the following hydraulic path:

Overland flow: average grass, $80ft$ long, $2\%$ average slope

Shallow concentrated flow $($unpaved$)$: $450ft$ long, $5\%$ average slope

Channel flow: $339ft$ long, $1\mathrm{.}9\%$ average slope and $n=0\mathrm{.}03$
