Not specific but they are values of resistance to flow through pipes, elbows, taps etc. etc. , there are names for the unit but I cannot recall any of them The unit would be normally be Ohms ( volts / current ) in electrical circuits

Unfortunately, the "resistances" are not as friendly in hydraulics as they are in electronics.
Your R1 and R3 are dependent on both the geometry of the pipe (as expected) and on the flow rate - which makes it all much more complicated.
and temperature ( viscosity ). But let's keep it reasonably simple to begin with. Calculations with accuracy of +/- 10 % will be OK here
Jesus you boys are unbelievable! Is this day to day "plumber" stuff or is this specific to heating? Or both?
I had no idea it was so involved!
How often are you calculating this stuff or is it a case of time served knowledge in this situation you need a b c and pipes of d e and f?

I do use Google to find copies of public domain documents. It is the other search engine that is better at fnding obscure information, but it costs money for the subscription
