A two-hour duration storm event with uniform excess rainfall of 3 cm occurred on a watershed. The ordinates of streamflow hydrograph resulting from this event are given in the table.
\[
\begin{array}{|c|c|}
\hline
\text{Time (hours)} & 0 & 1 & 2 & 3 & 4 & 5 & 6 & 7 \\
\hline
\text{Streamflow (m}^3/\text{s}) & 10 & 16 & 34 & 40 & 31 & 25 & 16 & 10 \\
\hline
\end{array}
\]
Considering a constant baseflow of 10 m\(^3\)/s, the peak flow ordinate (in m\(^3\)/s) of the one-hour unit hydrograph for the watershed is \(\underline{\hspace{2cm}}\). (in integer)
