Using Rational method, estimate the $10-$yr peak discharge from a $35-$acre watershed using the IDF curve from Problem $4.$ Assume Asphaltic developed areawith the principalflow pathbeing paved surfaces including gutter flow. The principal flowpathhas a length of $1800$ ft and a slope of $2\%$and velocity of flow $1\mathrm{.}28$ ft$/$s$.($Hint: Tc$=$ L$/60$v$)$
