Is the flow velocity of the fluid in a pipe related to the medium?

Is the flow velocity of the fluid in a pipe related to the medium? If the fluid in the pipeline is lubricating oil, what is the maximum flow velocity? :), if it’s fresh water, can the flow rate be infinitely high?
The flow rate cannot be infinite; when choked flow is reached, increasing the differential pressure will not increase the flow rate.
Different media have appropriate flow velocity ranges under different operating conditions; refer to: Pipe diameter selection HG-T 20570.6
Isn’t the velocity of a fluid also related to pressure?
Theoretically, if the pipeline can withstand sufficient pressure/friction, etc., the flow velocity can also reach infinity
Under normal circumstances, there is an economic flow velocity for a certain pipe diameter and medium
Could you share some relevant materials? Thank you:lol

Theoretically, flow rate is just a number that can be infinitely large; however, in practice, the flow resistance increases exponentially as the flow rate rises, making it impractical to transport such fluids. PS: The recommended flow rates vary for different types of media, and this is certainly related to the properties of those media; the most direct factor here is the difference in kinematic viscosity.
The Standard for Design Specifications of Steam and Water Piping in Thermal Power Plants (DLT5054-1996) recommends economic flow velocities for different media and pipe diameters.

Considering the corrosion resistance of metal pipes, measures should be taken to limit the flow rate in order to prevent an increase in the corrosion rate of the pipes. In the absence of relevant data and without access to advice on solutions, what is the recommended maximum flow rate for the fluid? 1m/s 2m/s 3m/s 4m/s Which option should be chosen for this question?
