Given:
T''(x)+ T'(x)2/x + sqrt(T(x)) = 0
values:
T(0)=1
T'(0)=0
solve T(y)=0 to get the value of y at which T is 0
and calculate the limit:
lim T'(x)
x>y
DE. Off hand, I do not see what physical phenomenon is being described by 
this equation. Is it some kind of homework problem
Simple as this looks, it still is a nonlinear and could be a bear to solve.
It does look somewhat familiar. Your best bet is to go to a library and look
at the book by Kempke that list many solved DE. It gives methods, but is in
German.
