Hi everyone;
we are going to transfer chemical from storage tank trough pump and pipe line to another plant.maximum flowrate is dictated by downstream plant and it is clear. i need to define normal flowrate because i need it for calculation and also to put it in equipment and instrumentation datasheet.i am wondering if anybody could give me an advice to define normal flowrate.
best regards

You are the only one who has that information. Or someone at the other plant if they control the flow.

Dear bobby;

control would be done in our plant but maximum flow as i said before is determined for us

If you are told to design a piece of equipment for a maximum flow rate, then interpret that to be your normal flow rate. Consider 'normal flow' to be the maximum flow you expect the equipment to see. Choose 40 m3/hr as the normal flow rate if that is the maximum flow in normal operation. The 'maximum flow' specified for a piece of equipment may include a safety factor (perhaps 15% to 25% higher) above the 'normal flow' for the possibility that occasionally you might need the specific equipment to be able to handle higher flow rates.
