3kg/s of a salt solution is concentrated from 10% to 55% solid in a backward feed double effect evaporator using steam at 393 k, and a vacuum such that the bubble point in the second effect is 325 k the feed is initially at 297 k and each effect is identical additional information 1 cpis 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= 25 kw/m²k second effect= 20 kw/m²k 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 2 degrees k and at, is decreased by 2 degrees k 51 draw the flowsheet for this process and define the applicable operating conditions for each effect 52 calculate the flowrate of the product steam and the amount of liquor evaporated? 53 calculate the steam consumption required?
