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?

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.

brian made this table to organize his notes on changes of state. depostion is a change of state that has the wrong energy change listed. it is utilized to collect data as a portion of the development means and in restricted conditions which may be applied at test.

a deposition in the authority of the united states or research for development in the authority of canada includes the catching of affirmed. the out-of-court verbal assertion of a spectator that may be lessened to a printed record for succeeding application for discovery purposes.
