What is the relationship between flow rate and pressure? ? ?
Thread Content
Now the customer has provided a flow rate value, as well as pressure and temperature, and the nominal diameter of the equipment; however, the flow velocity hasn’t been given. How should I determine the flow velocity when calculating the flow rate? ? How can we ensure that the customer’s traffic requirements are met? ? ?

Different nominal diameters have respective measurement ranges; simply select the instrument based on the flow rate value.
The question raised by the original poster isn’t very clear
The flow rate can be set directly according to the medium and relevant standards.
By providing the flow rate value and the inlet diameter, the flow velocity can be calculated...

The question is too vague – what device? What medium?
I didn’t understand your question. You provided the flow rate value as well as the nominal diameter; it should be possible to calculate it then, right?
If flow rate and diameter are given, why is flow velocity still needed...
