Heat loss, pipe size and BTU

I have some extra 1" copper pipes left over from an extension I did and thought that I can use them to convert some radiators that are currently connected to a steam boiler over to a 2 pipe hot water boiler.
The heat loss for the room is about 150,000 there are 6 cast iron radiators to be converted.
After looking at the piping chart here http://www.comfort-calc.net/pictures/Piping_chart.JPG I got a little concerned.

My question is will it work or do I need a larger pipe size or can I get away with a hi volume pump?

Not enough info...
You could bring the return from each rad back to the boiler room, or a selection of rads to add up to what is the max BTU you should try to push through 1" pipe.
