Answer / mohan

several small volume exractions are quiet best than the
single exraction..coz thr may be a chance for getting the
undesired product,i mean we dnt get the desired
quality..and also the feed must not be fully extracted in
case of single exraction,moreover it takes much time to
extract the feed..but in multi extractions with small
volume fullfill the drawback from the single extraction..it
takes less time to extract the feed..

Question 40 - A stream with volumetric flow rate Q enters a cylindrical tank and a stream with volumetric flow rate q exits the tank. The fluid has a constant heat capacity and density. There is no temperature change or chemical reaction occurring in the tank. Develop a model for determining the height of the tank, h. Let V is the volume, A is the cross sectional area, r is the density, m is the mass, where V and A are for the tank, r and m are for the fluid. The rate of mass of fluid accumulation, dm / dt = (Q - q) r. Prove the model to be dh / dt = (Q - q) / A.
