    If the air velocity is below this value, the solids will ultimately settled at the bottom of the pipe and block the pneumatic transport line. The pick-up speed is the conveying air velocity at the point of introduction of the solids in the conveying pipe. In order to be able to transport the solids, the pick-up speed must be higher than the

  • Air in Water PipesCEE Cornell

    Now, the general belief is that if you have air in the pipes you need to get rid of it so that the pipes will run full. This is because the presence of air often increases the head required for a given flow. In fact it is not at all rare that this air acts as a block so that no water at all comes out at the end of the pipe.

  • How to Calculate Compressed Air Consumption

    Air Jets utilize the Coanda effect (wall attachment of a high velocity fluid) to produce air motion in their surroundings.
