Unfortunately, recommendations aren't that straightforward because you also need to account for water pressure, material friction and more. All process calculations are based on the volume of the pipe which is the function of internal diameter of the pipe. A lot has changed over the years in terms of flow meter technology; however, you can’t argue with physics. That is why there was so much discrepency with the tables. Any flow meter employing one of these technologies will have a published specification for the range of velocities that it is capable of measuring. A wider pipe also produces a higher volumetric flow, and a shorter pipe lets a similar pressure drop provide a greater force. Also the longer the pipe the more time there is for these factors to produce more pressure drop and therefore the need for higher pressure at the inlet for a give flow rate. Here are the equations used for calculating flow-rates and predicting flow-rates. Determine the diameter of a pipe system to meet certain specifications.
