Juice is evaporated in a 2-stage process. Juice containing 6% solids enters the first evaporator. It leaves the first evaporator and enters the second evaporator at 18% solids. 400 kg/hr at 36% solids leaves the second evaporator. Calculate the water removed from each evaporator, the feed rate to the first evaporator and feed rate to the second evaporator.
