Q$.1.$ Calculate the amount of water required $(k\frac{g}{h}r)$ in a heat exchanger that cools down $100$

$k\frac{g}{h}$ of corn slurry from $90C$ to $30C.$ The slurry contains $30\%$ solids from a corn

variety having $70\%$ starch, $10\%$ protein, $4\%$ oil, $10\%$ fiber and $6\%$ ash on a dry basis.

The inlet water temperature is $10C$ and the heated water temperature is not to exceed $40$

$C.$ The datum temperature for this problem should be assumed to be $10C?$ points
