Webto the flow in a surface lying parallel to the lines of flow. The pitot static tube is an example of this. Figure 4 shows the principle of the pitot static tube. It will be seen that connecting tubes to a manometer makes the measurement of pressure. Page 7 . Figure 4. Principle of the pitot static tube. WebThe PVM620 is a rugged, compact, comprehensive micromanometer that measures pressure, and calculates velocity and volumetric flow rate. It can be used with Pitot tubes to measure velocity and then calculate flow rates with user–input duct size and shape. The PVM610 is an easy to use, hand held digital micromanometer for fast, accurate and ... fie full form

WebAlthough this pitot tube airflow calculation tool allows you to enter “Pitot tube correction (K) factor”, we suggest you use this tool only for pitot tubes with a manufacturer’s listed K factor of one. The devices we know of … WebUnder Pitot tube reading (velocity pressure, inches of water) read air velocity, feet per minute. Determining Volume Flow Once the average air velocity is know, the air flow rate in cubic feet per minute is easily computed using the formula: Q = AV Where: Q = Quantity of flow in cubic feet per minute. WebFollow instructions printed on the Dwyer Air Velocity Slide Chart included with each Pitot tube or use the following equations. Air velocity = 1096.7 where Pv — Sensed pressure difference (velocity pressure) in inches of water column = Air density in pounds/cubic foot (dry air = .075) D = Pitot tube coefficient— 1.0 Air Density -1.325 x PBT greyhound racing syndicates
