Steam velocity

Does reduction of pipe diameter have an affect on steam velocity ? I have a few radiators that branch off the 2 inch main with 1 inch pipe . thank

Of course. For a given amount of steam, the smaller the diameter pipe will have a greater velocity. However, the smaller diameter pipe will also have more friction, so the amount of steam which can be run through a small pipe for a given pressure difference will be reduced.

The size of the branch piping to each radiator is based on the the heating capacity of the radiator. It also depends on the type of system you have (1 pipe or 2 pipe).

Cant cheat on the pipe size (especially on 1 pipe systems) as the condensate flows counterflow to the steam.

you got three radiators on a 1'' pipe??
