In an arithmetic sequence $\{a_n\}$, the common difference $d=4$, and $a_2+a_5=22$. Let $S_n$ denote the sum of the first $n$ terms of the sequence $\{a_n\}$.
$(\text{I})$ Find $S_n$;
$(\text{II})$ Let $\{ \frac{n}{(2n+1)S_n}\}$ be a sequence, and $T_n$ be the sum of the first $n$ terms of this sequence. Find $T_{14}$.
