Re: Pipe diameter

Normal flow velocities through a water pipe are 2-2.5 m/s. This can be used to size the header pipe. Pressure drop in this pipe should not have a significant influence, as a large pressure drop seems to be over the nozzles. Thus maldistribution of the flow is excluded. If the nozzle tie-ins into the...

Re: Air flow

Is there a flow meter somewhere in the line? If this is showing the correct figure, there will be sufficient flow independent from the pressure drop (provided that the calibration was done correctly). If flow is adjusted by a volumetric pump (e.g. piston, diaphragm, displacer or flexible tube pump) ...

Bevel on orifice plate

A standard gas flow measurement orifice is equipped with a standard bevel on the downstream side. This is considered in most of the commercial orifice calculation programs. Does anybody have an idea, how to calculate the dp in case the orifice plate is installed in the wrong direction (i.e. bevel to...
