Question

Fresh orange juice contains approximately 10.0 wt% solids (sugar, citric acid and other indigenous ingredients) and frozen concentrate contains approximately 42.0 wt% solids. The frozen concentrate is obtained by evaporating water from the fresh juice to produce a mixture that is approximately 61.0 wt% solids. However, so that the flavor of the concentrate will closely approximate that of fresh juice, the concentrate from the evaporator is blended with fresh orange juice (and other minor additives) to produce a final concentrate that is approximately 42.0 wt% solids. Assume a basis of 100.0 kg of fresh juice fed to the process.

What is the mass of final concentrate produced? kg

What is the fraction of fresh juice that bypasses the evaporator?
