1. A solution containing 50 % KOH is fed at a rate of 1000 mol/h to an evaporator to produce a concentrated solution containing 80%mol KOH. The concentrated solution is then fed to a crystallizer to produce a filter cake containing 90 % pure KOH and 10% mother liquor (60% KOH solution). The rest of the mother liquor (60% KOH solution) is recycled back to the evaporator. Determine the values of B, C, P and W. Refer to the figure below. H0 w F-1000 mole/ SON by mole KOH 8, RO KOH P, pure KOHfiter 10% (6O KOH solution) GOS KOH

Steady State Model

The steady-state model typically states that the entire universe is always enlarging, although it balances a fixed average density and matter that is being constantly generated to make new galaxies, star forms at a similar rate that the previous ones get indistinguishable due to the growing range and velocity of recession.
