2.4 Dimensionless factor of reduction of speed
through an equalization device, being a function of bends, valves,
etc. in the cross-flooding system:
Values for k can be obtained from appendix 2 or other appropriate
sources such as computational fluid dynamics (CFD) or model testing.
If other appropriate sources are used, then the +1 factor in the formulae
may not be appropriate. CFD can also be used to evaluate the discharge
coefficient for the whole cross-flooding duct.
