Flow Measurement - Pitot Static Tubes Bernoulli's Equation etc.?

AI Thread Summary
A Pitot-static tube measures air velocity using a water manometer, with a deflection of 12.4 cm indicating the pressure differential. The air density is given as 1.25 kg/m³, while the water density in the manometer is 1000 kg/m³. To calculate air velocity, Bernoulli's equation is applied, utilizing the pressure differential derived from the manometer reading. The discussion emphasizes the importance of understanding pressure differentials in flow measurement. Proper application of Bernoulli's principle allows for accurate determination of air velocity.

A Pitot-static tube connected to water manometer is used to measure the velocity of air. If the deflection between the two arms of the manometer is 12.4cm, determine the air velocity when the density of air is 1.25kgm-3 and the density of the water in the manometer is 1000kg/m3.

I am not really sure where to start as i don't have the pressures...do i?

Thanks

You have the pressure differential since you have the difference in height of the two sides of the manometer.
 
Thank you for your reply, so what equation do i use from here? My pressure differential is 12.4 cm?

Thanks
 
You already said it. Bernoulli.

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
