3. Determination of refractory systems
The determination of these systems is analogous to that of fully moulded sand fillers, with or without in-mould filtration. ; however, the calculation of their pressure losses is a little more complex.
3.1 Estimated pressure losses and B coefficient
Readers are referred to the § 1.2.
We have already seen with moulded systems that pressure losses are of two kinds:
regular head losses, which are proportional to the length of the pipes ;
local or singular losses.
So, as with molded systems, we propose to express singular pressure losses in fictitious lengths, which can be added to actual...
