Hot water at 95°C is used in a plate heat exchanger for heating 2 kg s-1 fruit juice from 45°C to 75°C. Specific heat capacity of fruit juice is 3.7 kJ kg-1 K-1. Final temperature of the hot water is 70°C. Overall heat transfer coefficient is 1122 W m-2 K-1. Heat transfer area is 12.75 m2. The log-mean temperature correction factor is
Correct : 0.69
