Statutory Documents - IMO Publications and Documents - Resolutions - Maritime Safety Committee - Resolution MSC.362(92) – Revised Recommendation on a Standard Method for Evaluating Cross-Flooding Arrangements – (Adopted on 14 June 2013) - Appendix 2 - Friction Coefficients in Cross-Flooding Arrangements -

  k=1.7968 x (0<Li <12)
  k=1.684 (12≤Li )

 where:

  • k friction coefficient related to each space between two adjacent girders
    Li Length of the duct in meters

 Note: k is evaluated with effective cross-section area therefore in calculations use the real cross-section area A and not Sequiv. The pressure loss for entrance in the first manhole is already computed in the calculation.
