for the preparation of potassium nitrate, 10000 kg/h of a 20% kno3 solution is mixed with a recycle stream and sent to an evaporator. the rate of evaporation is 1.25 times the rate of introduction of recycle stream. the concentrated solution leaving the evaporator contains 50% kno3. this is admitted to a crystallizer which yields crystals containing 4 % water. at the crystallization temperature, the solubility is 60 kg/100 kg of water. major part of the mother liquor leaving the evaporator is returned to the evaporator as recycle. calculate: a. the concentration of kno3 in the stream entering the evaporator. answer 26.56% b. kg/h of recycle stream. answer 6000 kg/h c. the rate of production of crystals. answer 1816.24 kg/h
