Foam Backpressure Calculation for Tank Base Injection
Foam Backpressure Calculation for Tank Base Injection
(OP)
I am currently trying to size the line from a high backpressure foam generator to a base injection unit on a fuel storage tank and I am having trouble finding general mechanical properties of expanded foam to determine the likely pressure drop/backpressure.
The Foam is 3% AFFF.
Are there any rules of thumb to cover this?

When calculating downstream of the foam generator, I assume calculations are then based on the aspirated foam velocity/density to generate friction, rather than the non aspirated upstream rate with everything else based on Water and C = 120 for Galvanised Pipe? (ie I will need a proportionately larger line size downstream)
