Esteel        = 4.32 * 109 lb / ft2

Gsteel        = 1.73 * 109 lb / ft2

Do        = 1.750 ft

T        = 0.625 in

Di        = Do – 2*T = 1.646 ft

A        = π/4*(Do2-Di2) = 0.278 ft2

EA        =1.200 * 109 lb

M        = (ρsteel * A) * 110% (couplings) + MP + MMOD = 14.263 slugs /ft

ρ        = M / A = 51.337 slugs /ft3

Dd        = 3.917 ft

V        = (π/4*(Do2)) + (VMOD * NMOD / L) + VP

 = (2.405 + 6.400 + 0.450) = 9.255 ft2
