"All inputs must be positive". This is an initial check of user input to the pipe flow rate calculator. "d, D, d/D, or ReDout of range". The equation for discharge coefficient, C, is only valid for certain ranges of d, D, d/D, and ReDas shown in the Discharge Coefficients sect...
The calculator is doing calculation according to ISO 5167-2. You can expect to have correct and reliable results only if the orifice plate meets the conditions from the standard. What are the standard ISO 5137-2 conditions? For the flow of a perfect gas, the pressure loss created by the ...
Read on to understand how this calculator assists you in determining the mass flow through an orifice. What is an orifice and orifice flow rate? An orifice is a plate with a hole or cutout attached to the outlet or inserted inside a pipe such that the flow passes through the orifice. Th...
High Accuracy and Precision: The Intelligent orifice-plate flowmeter offers an accuracy of 0.5% and 1%, ensuring precise measurements for various applications. Wide Operating Range: This flowmeter can operate in a wide temperature range of -50°C to 550°C and can measure flow rates with a ra...
Discharge of Air Through An Orifice Equation and Calculator - Moss Formula The table given below gives the discharge of air through an orifice in cu. ft. of free Air per minute at atmospheric Pressure of 14.7 psia, and 70 °F Based on 100% coefficient of flow. For well-rounded entrance ...
Orifice flow meters are used to determine a liquid or gas flow rate by measuring the differential pressure (P1- P2) across the orifice plate. The two standard pressure tapping arrangements for small bore orifices are shown in the drawings; the location of the pressure taps affects the discharge...
