Pipe diameter calculation problem
Thread Content
I need everyone’s help with a question! ! ! It is found that the safe flow velocity of hydrogen in stainless steel at 1–3 Mpa is 25 m/s. The required flow rate in the pipeline is 2000 L/min (120 m3/h), with a pipeline pressure of 1.2–2 Mpa. How should the pipe diameter be calculated? Is the safe flow rate specified in the standards the operating condition flow rate? Does the flow rate need to be converted to operating condition flow rate?
Under all operating conditions, conversion is required. The flow rate is determined by converting the operating flow rate and pipe diameter into a flow rate value
Thank you! When changing the hydrogen flow rate from standard conditions to operating conditions, is it necessary to take the compression factor into account in the calculations?
No, there is no need for such high precision.
What is queried are the flow rates under operating conditions; simply calculate the flow rate as the operating condition flow rate to determine the pipe diameter
