A Study on the Dynamic Loss Coefficients of Non-standard Fittings in Ship Exhaust Gas Pipes [PDF]
As exhaust gas systems of ships become more complicated, it is necessary to calculate an accurate pressure loss at their design stage. If the dynamic loss coefficients of non-standard fittings mainly used in exhaust gas pipe (EGP) are well-documented, it
