Pipe Design

Pipe Design

Pipe Design

(OP)
I am currently working on re-designing a pipe run for a hydro test tank.  Knowns: max working pressure; capacity of tank; pipe material.

I am trying to determine the size of pipe required.  I reviewed MIL-T-16420 and have narrowed down my selection of pipe based on the classification of the pipe (70-30, No. 715, class 1650).  My question is when it comes to selecting the pipe diameter, is it simply my choice which pipe size to use?  I feel like O am missing something and I want to check with some outside sources to get some feedback.  Thank you in advacne for your help.

RE: Pipe Design

The choice is yours.  The selection narrows when you know the flow rate.  In this case, I'm guessing that's governed by how long you can wait to drain/fill the tank and/or the test article.

From flow, you get the size by selecting a limiting velocity.  

Pick a velocity and state it publicly here to start an argument.

RE: Pipe Design

hello,

it is not always a choice.
if you are going to enter a pump you are limited by velocity as our friend mentioned in his response.

Thank you for all the input.  Since the current pipe arrangement does not impose a problem in regards to the flow.  We will be using the same size pipe for the new arrangement.
