Consider a double effect forward fced Evaporator as displayed in the figure pelow. The saturation pressure of the steam being fed into cvaporator 1 is 100Kpa and the . 2 Q L 4 caving the evaporator 2 1... The concertrate of the feed and the liquid leaving evaporator 2 is 10% and 50%, respectively. Feed temperature is 30C. Assume: 1. The heat capacity of the liquid solution is 4KJ/kgK (constant) 2. The BPR0C=x2+2x+3 ( where x is solution concentration in fraction) 3. U1, U2 are 1000,2000 . W/ m2K, respectively. 4. H1=H2+2(BPR1) and H2=H1+2(BPR1) H1,H2,H11,H2 are Enthalpies and Saturation Enthalpies of streams I and 2 , respectively. 5. Vt=2V2 and areas of evaporator 1 and 2 , are equal. 6. The heat transfer of the process is at steady state conditions. 7. Feed rate entering the Evaporator is 20000kg per hr. 8. Rate of heat transfer in evaporator 1 and 2 are equal. No entraiment of solids in vaper Calculate: L1,L2,V1,V2 and total Steam Rate S (all in kg /hr) required
