Extracted text: 2. The capacity of a certain filtering equipment is defined as the volume of the filtrate (V) per total time per run. The total time of run is t = tf + tw + tc where tis the total time per run tf is the filtration time tw is the washing time, normally 1/5 of tf t, is the assembling and dismantling time, constant at 7 hrs per run The volume of the filtrate (V;) is a function of tf, is given by: Vf = 150/tf + 0.15 Find the maximum capacity of the filtering equipment with respect to the filtration time tr.
