Notes:

Weight and allowable
stress calculations are based on steel pipe material
having a 490 pcf density and a modulus of elasticity (E) of 29,000 ksi.

Buoyancy calculations based on pipe submerged in seawater having a
64.2 pcf
density. Full buoyancy will not occur for open-ended pipes.

Pipe allowable
stresses based on equations provided in American
Petroleum
Institute's Recommended Practice 2A - Working
Stress Design (API RP 2A-WSD)
21st Edition.
