    Optimal IP

    NH3 system, single stage, pumped liquid with open flash economiser (no subcooler) at IP going to screw compressor economiser port.
    LP at -18degC/105kpa,
    HP at +30degC/1065kpa.

    How do i determine what is the optimal IP?

    I have seen this equation Pip=sq root(Php x Plp) psia and that would equate to 390kpa and the site manual states 190kpa.

    Thanks in advance.
