To calculate air velocity in a pipe, you would need to measure either the volumetric flow rate or the mass flow rate of air flowing through the pipe. You can then use the formula: air velocity = volumetric flow rate / cross-sectional area of the pipe, or air velocity = mass flow rate / (density of air * cross-sectional area of the pipe).
To calculate the velocity of air in a mine, you can use a device called an anemometer. An anemometer measures the flow and speed of air, providing you with the velocity information. Simply place the anemometer in the air flow in the mine and it will give you a reading of the velocity.
The velocity pressure can be used to calculate the velocity of air in the duct using the formula: velocity = √(2 * pressure / air density). Assuming standard air density and converting 0.20 in w.g. to the appropriate pressure unit, the velocity of air in the duct would be approximately 903 ft/min.
Air escaping from a small pipe produces more noise because it is being forced through a smaller opening, creating a higher velocity and turbulence in the airflow. This turbulence causes vibrations in the surrounding air, which we perceive as noise. In contrast, air escaping from a large pipe has more space to flow through, reducing the turbulence and noise generated.
Air nozzle velocity can be calculated using the formula v = sqrt((2 * P) / ρ), where v is the velocity in meters per second, P is the pressure in pascals, and ρ is the air density in kilograms per cubic meter. Simply input the values of pressure and air density into the formula to determine the air nozzle velocity.
In a pneumatic line, the layer of air closest to the surface of the pipe moves more slowly compared to the other layers due to the effect of friction between the air and the pipe's surface. This phenomenon is known as the "no-slip condition" and causes a velocity gradient in the air flow profile across the pipe diameter.

Mass flow in air can be calculated if you know the pressure drop across the pipe. Then it can be calculated using Darcy's Equation for Pressure,which is: P2-P1 = (4fLv*v)/d*2*g where, P2 & P1 are pressures at two points in pipe, f = friction factor, L= length of pipe, v = velocity of fluid, d = diameter of pipe, g = gravity. from this formula we can calculate the velocity and hence the flow rate.
Yes, it is actually one of the questions on a master plumbers exam
Critical velocity is that The Liquid Air flow in narrow pipe constatly.
When air is blown through a pipe of paper, the increased air pressure inside the pipe builds up, causing the paper to bend and squeeze. This is due to the difference in pressure between the air inside the pipe and the air outside. The paper bends to release this pressure and equalize it with the outside air.
Static pressure is .434 X height Example 10 ft x .434 4.34 PSI to prove take 2.31 PSI x 4.34 To find FORCE to need to calculate the diameter of the piping and the height and then the weight of the water inside the pipe

To calculate pressure in pounds per square inch (psi) for a fluid flowing through a pipe, you need the fluid's density. Without knowing the density, we cannot directly determine the pressure using just the pipe size and velocity. The pressure would depend on the specific fluid being transported in the pipe.
The velocity of a fluid particle at the center of a pipe in a fully developed flow is half of the maximum velocity in the pipe. This is known as the Hagen-Poiseuille flow profile for laminar flow.
