QUESTION 2 A forward feed double-effect evaporator is required to concentrate a orange juice mixture from 4% to 80% using steam at 320 kPa. The feed enters at 1 200 kg/hr at 303 K and the first effect is operated at 110 kPa. Additional information: Cp is taken to be 4.18 kJ/kg.K Boiling point rise can be neglected D=D2 SPP3701 Assessment 05 2023 S1 1 The overall heat transfer coefficients are as follows: First effect= 2.8 kW/m. K Second effect= 2.8 kW/m. K 2.1. 2.2. Calculate the steam economy. Calculate the required steam consumption. (13) (3) 2
