Calculation of the maximum flow rate for steam pipelines

There is currently a steam pipeline with a diameter of DN250; the steam temperature ranges from 230 to 270 degrees, and the pressure is around 0.62 to 0.75 Mpa. I would like to know what the maximum flow rate is, and whether it is sufficient to meet a demand of 25 t/h. I calculated earlier at 40 m/s, and the inner diameter needs to be around 270–280. I installed it by using the formula shown in the diagram
I wonder how people generally calculate the minimum flow rate? Or do you have any practical experience with typical flow rates?:)
To calculate the flow velocity, it is necessary to consider both the pressure drop; both factors must be taken into account
This is related to the pressure and length of the pipeline required in your end use. Whether it’s possible to transport 25 t/h depends on your specific requirements. However, the flow velocity in the pipeline is assumed to be 40 m/s; if the pipeline is long, then the pressure loss will be significant.
Flow rate cannot be calculated without knowing the pressure drop
The calculated pressure drop can be considered acceptable if it is less than the actual pressure drops in the pipelines before and after
