Process parameters: flow rate of 370 cubic meters per hour; the medium is an aqueous solution with viscosity similar to that of water and a density of 1.14 g/cm³. The filter element currently selected has a filtration area of 0.37㎡ and a filtration precision of 100 mesh, resulting in an effective filtration area of 0.37*0.4*0.4 = 0.0592㎡. Since the medium is an aqueous solution, and using a flow velocity of 1 m/s, the diameter of the inlet and outlet pipes is DN350, with an area of 0.096㎡. According to standard SH3411, the filtration area of this filter is 0.096*3 = 0.288㎡. Based on this, the number of filter elements required is 0.288/0.0592 = 5, which determines the diameter of the equipment. Please advise whether the above calculation process is reasonable. Other issues such as pressure drop are not considered.
