Restriction Testing

Continuing the same test method as before, I’m measuring restriction or pressure drop over the range of possible flow rates to get a complete look.  I simply increase flow across the radiator at .5 GPM increments and record the pressure drop across the rad via manometer.  My flow meter is a King Instruments 7520 with valve, my manometer is a Dwyer 477-5 digital manometer, and I have fabricated my own 1/2″copper x 1/4″ brass T fittings to avoid adding restriction to the test.

Radiators are generally pretty low in restriction, so this is normally not something to worry about much unless you plan to run several radiators in series.

First the detailed results:

Followed by a comparison:

I included my previous CPU block testing so you could get some feeling of scale.  As previously mentioned radiators are generally very low in restriction and the RS360 is fitting of that.  The RX360 was also included so you can see how a double thickness radiator of similar two pass design lowers restriction even more.  The RX360 has the advantage in providing double the amount of tubes for water to pass through.
