I don't know that anyone has optimized this.  Depending on the size of
your tank the ideal flow rate probably would be more readily measured in
drops/minute than in gallons/min.

It won't give your plants the "warm feet" effect that people get from
heating cables.

I do this and it works well - it may actually give too much flow.  The
flow can be regulated with a valve or possibly with a drip irrigation flow
regulator.  Obviously your mileage will vary.
