The last geometrical similarity condition can be relaxed depending on the de-
gree of similarity required. For example, the transverse area condition is
important only where the heat transfer is significant because the velocity
simulation in adiabatic sections is not important. In terms of the axial
length similarity condition, it is important that Eq. (54) is satisfied in
the hot leg section such that the driving head is well simulated. When Eq.
(54) is partially violated, it is very important that Eq. (23) is satisfied
such that the fluid transient time over the entire loop is correctly simulated.
Hence

Li/Ai R = 1
In view of Eqs. (46) to (49), it becomes

Stanton number criteria. On the other hand,
it is almost impossible to satisfy them in a
increased power demand in a model.
