Saturated steam with 120.8 kPa is used to concentrate 1000 kg/h of juice from 12% to 20% solids at 95°C (steam and juice have no contact). After concentration, the stream water becomes water condensate. Assume that the heat capacity of juice is 4 kJ/kg°C, calculate how much steam is required to achieve this operation.
