How do I calculate the void space in a column? Actually we are putting ½-inch balls in a 14-inch pipe. Height of packing will be 3 inches. Above the ½-inch balls we will put ¼-inch balls and the packing height will be the same (3 inches). How many balls can I put in the column?
Have an insight or suggestion?

30 November 2009 at 1:29pmA packed bed makeup of a perfectly spherical shape always has a void space of 40%. Void space is greater where the sphere contacts the pipe wall. I am sure that Dr. Hassan Niknafs of Saint-Gobain Hassan.Niknafs@saint-gobain.com can provide you the information you need because his company manufactures and sells balls and pellets for packed beds.
