Adouble effect parallel evaporator is used to concentrate a sugar solution from b mass % to 25% and the total feed is split into a 80 20 ratio (80 is fed to the first evaporator and 20 into the second evaporator) the total feed enters at 25 °c at a rato of 5 000 kg/h the fresh saturated steam enters the first effect at 230 kpa (abs) while the second effect is operated at 13 kpa (abs) the flow rate of the steam is 2 500 kg/h additional information 1 cp is taken to be 4 18 kj/kg k 2 boiling point rise can be neglected 3 the overall heat transfer coefficients are as follows first effect = 3 33 kw/m²k second effect = 2 75 kw/m2k 4 perform only one iteratio 5 since the feed enters as a cold stream, the first effect requires more heat than the second effect at, must be increased and at2 must be decreased proportionately in this case, assume at: is increased by 25 k and at2 is decreased by 25k 41 draw the flowsheet for this process and define the applicable operating conditions for each effect (2) 42 calculate the flowrates of the liquid and vapour streams that enter and leave each evaporator (16) 43 calculate the steam economy
