8-7-31
L=8.5"
2.900"
1.000"
0.950
VANE 1.5" WIDE.
WL = p a l
∴ FOR 154 LB/□" PRESSURE W = (154 x 1 x 1.5 x .950) / 8.5 = 26.3 LB
W 60° I.S. = 154 LB/□"/IN: = 26.3 LB. BALL PIN LOAD/IN: DIAGRAM
120° I.S. = 308 LB/□"/IN: = 52.6 LB. BALL PIN LOAD/IN: DIAGRAM
180° I.S. = 462 LB/□"/IN: = 78.9 LB. BALL PIN LOAD/IN: DIAGRAM
