Apple juice is life tight in a natural-circulation single-eff ect evaporator. At steady-state conditions, enervate juice is the pamper introduced at a objurgate of 0.67 kg/s. The energy of the enervate juice is 11% entirety solids. The juice is tight to 75% entirety solids. The unfair heats of enervate apple juice and concentobjurgate are 3.9 and 2.3 kJ/(kg °C), respectively. The fume constraining is measured to be 304.42 kPa. The opening pamper region is 43.3°C. The issue internally the evaporator boils at 62.2°C. The overall heat-transfer coeffi cient is conjectured to be 943 W/( m2 °C). Assume negligible boiling-point loftiness. Calculate the concretion issue objurgate of tight issue, fume requirements, fume distribution, and the heat-transfer area. The plan is sketched in Figure E8.1 .
