My 70+ year old home has hot water heat, with all radiators on a single thermostat. I wish to break the heat distribution up to at least two zones. Plumbing and demolition/repair are not a real issue. I'm concerned with the compansation of pressure drops with pipe diameter in order to balance inter-zone heat distribution. Are there any "rules-of-thumb" or standard design practices in this effort?
