added mass

[Seiya09]

Hello everyone,
I wanted to ask you a question:
in real constants, in inserting the values, the unit of measure that asks in
"added mass / unit length (addmas)" is n/m(mm) or kg/m(mm) ?

Thank you.

if you use the international measuring system see also help /unit, you have to express additional masses in kg/m
