At a site, Static Cone Penetration Test was carried out. The measured point (tip) resistance $q_{c}$ was $1000$ $\text{kPa}$ at a certain depth. The friction ratio $(f_{r})$ was estimated as $1\%$ at the same depth.

The value of sleeve (side) friction (in $\text{kPa}$) at that depth was _________________. (in integer)
