    need performance data

    Hey guys, I am seriously happy I found this site.

    I am an engineer and trying to do some pump sizing for a pool. However I am really having a tough time finding performance data on pool inlets. I need some data on some jacuzzi 2" directional eyeball inlets. Does anyone have a website, or some pdfs of the pressure/flow data I can take a look at. Even an equivalent would work.

    Thanks very much in advance.

    Thanks Bama. I worked it out and then actually stumbled upon an old chart showing pressure drops vs. flow for different orifices. My calcuylation was consistantly 2ft. head higher than what the chart was displaying. Works out well.
