† Weights are based on low-carbon steel with a density of 0.2833 lb/in3. For other metals multiply by the following factors:
Aluminum...........................................0.35
 
Aluminum brass....................1.06
Titanium..............................................0.58
 
Nickel-chrome-iron..............1.07
AISI 400 series stainless steels...0.99
 
Admiralty.................................1.09
AISI 300 series stainless steels...1.92
 
Nickel and nickel-copper.....1.13
Aluminum bronze..............................1.04
 
Copper and cupronickels....1.14
↨ Liquid velocity = (lb per tube per h / C x sp gr of liquid) in ft / s [sp gr of water at 16oC (60oF) = 1.0]
