MIL-HDBK-1004/10
(4)
Anode current density is computed as follows:
Output
=
15.2/2 x 10 x 2
=
0.38 A/ft2
j)
Resistance of main anodes:
R
=
(0.012P log D/a)/L
where
P
=
4,000 ohm-cm
D
=
56 feet
L
=
2 x 5 feet = 10 feet
a
=
44 x 0.275 = 12.1 feet (0.275-equivalent diameter
factor from curve) (see Figure 100)
R = (0.012 x 4,000 log 56/12.1)/10
R = 48 log 4.628/10
R = 3.19 ohms
