Sampling from fluid streams of air, flue gas, steam, or any media that contains entrained particles is a very tricky affair. ... If the velocity is more, then more particles will enter the tube, again especially the smaller particles. Both conditions produce samples with wrong concentration. Ideally, the flow of the sample through the sampling ...

velocity tube, you can see if the air has a tendency to exit at an angle. With the velocity tube, and the 'Flowbee', I found that this port needed about 1/8" clearance from the top of the exit to the top of the header tube for maximum flow. If I moved the tube down any closer to the top of the exit, the 'Flowbee' indicated less air flow.
The pitot tube measures clean air flow in a coal pipe based on an internal grid of at least 24 individual measurements representing equal flow areas. ... A change in the velocities through the ...
CFM (Air Flow) Cubic Feet (of air) per Minute. ... but you wouldn't feel a thing if you inhale through a twoinch pipe. If you want to vacuum through a larger opening, you'd need more CFM. ... Another combination measurement of Waterlift and Air Flow is called Air Watts, which has become more standard for the central vacuum industry.
There are many aspects to be considered when a process line is designed. They can vary and be extremely complex, which places considerable demands on those responsible for the preliminary planning. ... Every component in the line offers resistance to the flow when a liquid is forced through a pipe system. In straight pipes, the resistance is ...
tube pitch is usually between 2 and tube diameters. Net free area for air flow through bundles is about 50% of face are rolled or welded into the tube sheets of a pair of box headers. The box header consist of tube sheet, top, bottom, and end plates, and a cover plate that may be welded or bolted on.

If the transport system can be run with ...
If a water pipe is 15 mm diameter and the water pressure is 3 bar, assuming the pipe is open ended, is it possible to calculate the flow rate or water velocity in the pipe? Most of the calculations I have found appear to need 2 of these: diameter, flow rate, velocity.
