How To Calculate Differential Pressure Of Flow. The general equation for mass flow rate measurement used by ISO5167 standard is. To verify this equation the value of k can be calculated using the first entry by dividing the flow rate by the square root of differential pressure. Technical note 12 Differential pressure mass flow meter rev. As another example a measured differential pressure of 110 inches water column across this orifice plate generated by a flow of gasoline specific gravity 0657 would correspond to a gasoline flow rate of 347 gallons per minute.
Enter the unit used for measuring differential pressure eg. To verify this equation the value of k can be calculated using the first entry by dividing the flow rate by the square root of differential pressure. Im assuming laminar imcompressible flow with negligible friction head or thermal losses this is a very low-flow system. The value of k thus obtained can be used to verify other entries by multiplying their pressure drop value by k or by dividing flow rate by k. An ASHRAE equation for Differential Pressure P in PA is. This creates a difference in the static pressure between the upstream and downstream side of the device.
