equivalent pipe method
equivalent pipe method
(OP)
i used the equivalent pipe method to determine the head of the pipe. the pressure drop across my device is known and is converted to head. now i have the total head of the system. to fall within the recommended pressure operating range of the device do i add head before selecting a pump?

Please take some time to explain what you are trying to do and what you have done so far.
Care to try again?

When in doubt, going back to the basic Bernouli's equation usually helps.
By the way, because this board gets a multiutde of people from around the world, all coming from different disciplines, communications skills are very important. It really helps us to help you if you:
(1) Use proper grammar, puncuation, capitalization, and spelling;
(2) Provide a diagram if at all possible (that overcomes any deficiencies in (1);
(3) Give way more detail then you think necessary, so no one is left guessing.
Big Inch -- I'm not really sure what he's talking about either. It sounds like he wants to add a head fudge factor before selecting his pump and is looking for someone to give him an ok.
