    Cooling tower piping design

    Context:
    Rectangular cross-flow cooling towers of about 200RT per fan, for water cooled chillers for commercial air-conditioning in a tropical climate.

    Some cross-flow cooling towers have piping arranged like in attached photo - incoming warm water pipe is submerged for a considerable length in the bottom basin, which seems sub-optimal.

    How much impact do you think this has on efficiency?

    I imagine there is a formula for estimating the heat flow from warm water thru a given area of PVC pipe into cooler water. Any pointers?
