WebMay 23, 2024 · To select the proper valve for the application, it is necessary to calculate the needed flow capacity (Cv). The necessary Cv will be dependent upon the pressure drop across the valve. The greater the pressure drop taken across the valve, the greater the flow through the valve. WebMany thermal design engineers use the following steps when designing an air filter: Select air filter dimensions (length, width, thickness). Calculate airflow velocity in linear ft./min. using air volume rating of fan in cfm divided by surface area of air filter in sq. ft. (i.e. 200 cfm./0.50 sq. ft. = 400 fpm) Select disposable or reusable media. dhl package delivery report
