In a process producing KNO3 salt, 1000 kg/h of a feed solution containing 10% KNO3 and 90% water is fed to an evaporator which evaporates some water to a produce a 50% KNO3 solution. This solution is then fed to a crystallizer where the KNO3 crystals formed are separated from the saturated solution. The saturated solution containing 35% KNO3 is recycled to the evaporator. All percentages are on a weight basis. Calculate the following: a) the mass flow rate of the crystals formed b) the mass flow rate of the water evaporated c) the mass flow rate of the recycle stream d) the mass flow rate of the solution leaving the evaporator
