A triple effect forward feed evaporator is evaporating a salt solution from 2 wt\% solids to 15% solids. BPR of the solution can be estimated from BPR=4.90x+15x2, where x is the weight fraction of salt in the solution. Saturated steam at 316kPa is being used. The pressure in the vapor space of the third effect is 47.4kPa. The feed rate is 15,000kg/h and the temperature 330K. If the heat transfer coefficients are U1=3000,U2=2000, and U3=1500W/m2.K, determine total temperature difference (T). No need to make any trial-error. 58.52 61.15 55.45 60 56.51 Bo birak A triple effect forward feed evaporator is evaporating a salt solution from 2 wt\% solids to 15% solids.
