Scale-up of Batch Filtration of Protein Precipitate A small test filtration of a pro- tein precipitate in an aqueous suspension uses a conventional filter with an area of 89 cm2 at a pressure drop of 0.4 atm to give data for the filtrate volume as a function of time (see Table P4.12). We would like to filter a much larger batch of the precipitate at the same temperature containing 1000 liters of solvent by using a filter of 1.3 m' area having the same filter medium as for the small-scale filtration. However, this larger batch has a concentration of 0.28 g/100 cm3 of solvent, less than in our test filtration, which is 0.34 g/100 cm3 of solvent. How long will it take to filter this new batch at the same pressure drop? What is the error in the calculated time if the resistance of the filter medium is neglected?

(Algebra: perfect square) Write a program that prompts the user to enter an integer m and find the smallest integer n such that m * n is a perfect square. (Hint: Store all smallest factors of m into an array list. n is the product of the factors that appear an odd number of times in the array list. For example, consider m = 90, store the factors 2, 3, 3, 5 in an array list. 2 and 5 appear an odd number of times in the array list. So, n is 10.)Here are sample runs:Enter an integer m: 1500The smallest number n for m * n to be a perfect square is 15 m * n is 22500
