Fresh tomato juice containing $6 \%(\mathrm{w} / \mathrm{w})$ total solids enters in a single effect evaporator at a feed rate of $500 \mathrm{~kg} \mathrm{~h}^{-1}$ to concentrate up to $36 \%$ (w/w) solids. In this process, the rate of water removal in kg $\mathbf{h}^{-1}$ (round off to 1 decimal place) is__________________
