Pipe pressure drop
Thread Content
What is the pressure drop for a DN250 pipe reducing to DN150? And what is the pressure drop for a reduction from DN250 to DN50? Thank you
How did you work out those figures?
It can be calculated using Bernoulli’s equation, but it also depends on your piping layout; you need to clarify all those details, such as whether it’s a concentric diameter change or something else
It’s necessary to understand what the corresponding pressure drop will be if using tapered pipes... Relevant data can probably be found in tables
