Japanese term or phrase: 広義の抵抗係数
The following passage is from a document regarding ship maneuvering and the related equations of motion.

次のような運動方程式が得られる。
M du/dt= −Tuu(u2 − Tuu − T0)
ただし
M = m + mx
Tuu = (1/2)ρSCD − (1 − tP )ρDP2 (1 − wP )2k2
Tu = (1 − tP )ρnP DP3 (1 − wP )k1/Tuu
T0 = (1 − tP )ρn2P DP4 k0/Tuu

M は見かけの質量、Tuu は速度の自乗に比例する広義の抵抗係数、Tu は速度に比例する係数、T0 は強制項である。Tu と T0 はプロペラ回転 nP の関数として表されることに注意が必要である。Tuu, Tu, T0 が定数の場合、(6.7) は変数分離型の微分方程式であり、その解は次のように表される。

English translation:overall resistance coefficient
Explanation:
(This rendering squares up with Katse_bro's specified meaning, while being simpler and more consistent with the technical style of the specification.)
so just rearranging the chairs on deck, and we are not sailing on the Titanic... :-)

mm! "overall' is perhaps too definitive. 広義 suggests a more approximate notion. , in this case, "broad resistance coefficient" could be sufficient IMHO...

Considering the various views contributed to this topic and some more look-ups, am inclined to reaffirm my conviction re: the appropriateness of 'overall' as a rendering for '広義'. See Post Discussion

coefficient of resistance in the broad sense


Explanation:
Exactly what it says on the tin. As opposed to Tu which is more specific.
Note: "broad sense" applies to resistance, not the coefficient.
