    Submersible pump heat gain

    THANKS hydrotools All water is recirculated within the system, and will be subject to ambient conductive and convection surface area losses which I need to calculate. DeltaHydro

    Submersible pump heat gain

    That is what I assumed, the obvious. I guess any sound power and vibration energies would be transmitted into the submerged water environment too oppossed to a dry mounted pump installation. So I'll assmue all wasted energy ~ 25% THANKS DeltaHydro

    Submersible pump heat gain

    Looking for a rule of thumb to estimate heat gained from a submersible pump in a temperature sensitive aquatic system. Have a 17.6 KW pump sized @ 75% efficiency, what precentage of wasted energy can I assume or calculate will be transmitted to the water system as heat? DeltaHydro
