Line Size
Line Size
(OP)
We have recd an enquiry where The line size or valve size are not specified by the client and we are asked to size the valve based on the given flow rate, Operating Pressure and Temperature. Can any one help me to find our minimum line size?

The web page shows a nomograph for the "economic diameter" of pipe that takes into account the flowrate, fluid density and a number of financial factors too involved to present here.
RE: Line Size
To size pipe when the pump is already determined you need to know the pressure drop available in addition to the pressure drop. This is a pure engineering calculation independent of economics.
