a Factor for Method of Manufacturing = Hand Lay-Up
K1 = 1.50
b Factor for Strength Loss = yes
Strength Loss = N/A
K2 = 1.30 SINCE TP LINING
c Factor for Design Temperature
[1.25-.0125(HDT-20-Dt)] HDT = 100 Degree Cel.
DT = 100 Degree Cel.
K3 = 1.00
d Factor For Cyclic Loading
Number Of Cycles in life time = 3650
[1.1+.9(log N-3)/3] K4 = 1.27
