In a batch process, the reaction takes place in the presence of an acid medium. The acid is drained from the reaction vessel at the rate of 15ml/s as a result of the density difference of the acid from the reacting component. To avoid wastage of acid, it is recycled to an acid tank which has 1000 L capacity. The acid drained from the reaction vessel, picks up 50 g/L solids from the reactor. Acid is fed once again to the process from acid tank. When the process is started, the acid is almost pure in the tank as a result of filtration. As the reaction proceeds, acid in the tank gets more and more contaminated with the solids. The concentration of the solids should not exceed 100 g/L from the process point of view. The batch time is 16h. Estimate whether the concentration of the solids will exceed 100g/L during the batch reaction.

A laboratory teacher had 1.5 litres of concentrated sulfuric acid. She replaces concentrated sulfuric acid with water after every class till the carton is empty. One student needs 10 ml of sulfuric acid mixture in every class. First class had 20 students and since then all other classes observed 10 students. Calculate total quantity of water with which mixture of sulfuric acid and water is replaced till carton is empty. Note 1.5 litres of concentrated sulfuric acid had 90% sulfuric acid and rest water
