26、08) 17 The basis and method of correcting the volume of spherical and smooth spheroidal tanks which have been affected by changes in temperature is described in Section 10. The coefficient, KI, is obtained from the curve shown in Fig. 7 which is based on a mean thermal expansion co- efficient, ant,
27、of 0.0000065 per deg F. The value, KI, taken from the curve must be adjusted to the actual thermal expansion, m, of the tank material at the actual tank temperature, t.
