If you roughly know the flow rate of a gas or liquid, how can you estimate the pipe diameter? Is there a difference between gases and liquids?

If it’s a liquid, I usually set the flow rate at 1 m/s, which gives an estimated flow volume of 28 m3/h for a 100 mm pipe. For saturated steam at 6 m³/h, what size is appropriate for a pipeline under a pressure of 7 kilograms? How is this calculated? What is the flow rate of saturated steam at a pressure of 7 kilograms per square meter for a pipe with a diameter of 200?
It is recommended to consult Table 2-716 in Volume 1 of the third edition of the Chemical Process Design Manual. Also, learn about HG-T20570.6. Finally, review* m=ρv, the formula for the area of a circle, and other basic concepts. You’ll understand this question completely; there’s no need to ask anyone.
It can be calculated based on volumetric flow rate or mass flow rate. The recommended flow velocity for fluids is specified in chemical process design manuals, chemical pipeline design manuals, or other relevant guides; it can be determined using the formulas Qv = uA or Qm = uAp. If pressure drop needs to be taken into account, the flow velocity must be recalculated accordingly.
