Q1] (10 marks) A plate and frame filter press has a rectangular filter, its length is two meter and equals twice the width. The filter press is operated with a pressure drop of 3100 mmHg. The total time of filtration cycle is 11.5 h while, the time of filtration is only a half of that. In a test with a small leaf filter (d=0.25 m), operating with a pressure difference of 525 mmHg, 125 cm³ of filtrate was obtained in 150 s and a total of 200 cm³ in 200 s. Estimate the optimum filtration time for maximum throughput.
