Help: Does anyone know how to calculate the pressure loss of a filter?
Thread Content
Are the pressure loss and resistance of a filter the same thing? The filter formulas found online do not take into account the filter media or flow rate.
This cannot be calculated; generally, once the pressure difference before and after the valve is known, the pressure loss is also determined. However, the flow resistance of different valves can affect the flow rate. However, when working with piping systems, pressure loss is taken into consideration, and the pressures before and after the valve are selected appropriately. Let me give you an example: if the pressure before the valve is 5 kilograms and it is vented after the valve, then the pressure loss is 5 kilograms. Therefore, it is incorrect to talk about pressure loss alone.
Filter pressure drop... I asked the manufacturer, and it seems there’s no specific formula for calculating it. From a purchasing perspective, one only needs to enter the pressures at the inlet and outlet; as for the pressure drop, apart from the opening status of the valves before and after the equipment, the degree of clogging of the filter mesh is the most important factor. So in essence, it depends on the type of filter mesh and filter to be used
