**Re Formula for calculating wind velocity through a tube**

3/03/2010 · You need a differential pressure across an orifice, pressure drop in a venturi or velocity pressure from a pitot tube. Once you get some form of velocity pressure (and if you give us more details about your setup, we can tell you how to measure/estimate it), you can use a form of Bernoulli's equation to find the velocity:... Air duct also termed as ductulator is a passage that is used to provide fresh air into rooms, buildings etc., Air ducts may be in circular, square and in rectangular shapes. This online air duct calculator is used to calculate the velocity of air flow feet per minute (FPM), and feet per second (FPS) through any shaped (circle, square or rectangle) ductulator with either diameter, sides or area.

**How to Calculate Air Velocity Sciencing**

Velocity of propagation is a measure of how fast a signal travels over time, or the speed of the transmitted signal as compared to the speed of light. In computer technology, the velocity of propagation of an electrical or electromagnetic signal is the speed of transmission through a physical medium such as a coaxial cable or optical fiber.... 12/06/2014 · Through this area, the mass flow rate is density (r) times velocity (Vp), times area. m dot = r * Vp * A Substitute this value for the mass flow rate into the thrust equation to get the thrust in terms of the exit velocity, entrance velocity, and velocity through the propeller.

## How To Find Vp In Air Velocity

Problem: Air flows in a 0.6 m diameter circular duct. At the end of a long straight run the centerline velocity is measured to be 9 m/sec. Estimate the average velocity and mass flow rate of the air assuming standard conditions for the air.

- Vp = l*f (2) here, Vp = phase velocity (m/s) l = wavelength (m) f = frequency (Hz) holds, the shortening coefficient of a wavelength is equivalent to the decrease in the ratio of velocity…
- To measure the velocity pressure, connect a Pitot or averaging tube to a velocity sensor and place the tube into the air flow of the duct. The actual velocity requires either a mathematical calculation or a calibrated sensor that directly shows velocity.
- Find: Calculate the air velocity in ft/s Assume: Steady, incompressible, isentropic flow of air; good alignment of pitot-static tube (streamlines parallel to stagnation tap and perpendicular to static tap); air …
- Velocity of propagation is a measure of how fast a signal travels over time, or the speed of the transmitted signal as compared to the speed of light. In computer technology, the velocity of propagation of an electrical or electromagnetic signal is the speed of transmission through a physical medium such as a coaxial cable or optical fiber.
