sizing compression tank

I'd like to know how to size a compression tank (diaphram). I'm using ci thin wall rads (six), with a total of 342 sq. ft. of radiation as figured out from Dan's book, "How Come". In the book he explains the transition from gravity to circs with large pipes. I'm using new correct size pipe so I'm able to calculate that part. But short of filling one of the rads with water and measuring the amount, I don"t know how much water all the rads will hold. Any info is much appreciated.

    Check with the manufacturer you bought them from. If anyone should know, they should.

    These rads are older than me. They were in the house when I bought it.
