$Problem \# 2: A single effect evaporator is to be designed$

Problem \# 2: A single effect evaporator is to be designed at the following operating conditions: - Tc=20C, and Ts=100C, then - Uc=Ue=2kW/m2C - Ls=2257kJ/kg. Ld=2330kJ/kg - Choose Tt=Tx4C,BPE=1C - F=2.5kg/s,D=1kg/s,C=4kJ/kgC Calculate: AcD and Ae/D for two cases: 1. Low TX is chosen equal to 40C 2. High Tx is chosen equal to 80C
