A double-chattels evaporator is substance used to concentrate fruit juice at 25,000 kg/h. The juice is 10% whole sound at 80°C. The juice must be concentrated to 50% whole sounds. Saturated fume at 1.668 atm is available. The condensing clime of the gas in the succor chattels is 40°C. The overall heattransfer coeffi cient in the fi rst chattels is 1000 W/( m 2°C), and in the succor chattels it is 800 W/( m 2 °C). Calculate the steameconomy and area required in each chattels, assuming the areas
