디젤유 탱크(Diesel Oil TANK : DOT) 소요용적
- 디젤유는 항해시 발전기 엔진(Generator Engine) 구동과 출입항 시 주기관 구동에 필요한 디젤유를 포함하여 그 소요 용적을 계산한다.

curvature of upper and lower surfaces. Foils of similar function designed with water as the working fluid are called hydrofoils.
The lift on an airfoil is primarily the result of its angle of attack and shape. When oriented at a suitable angle, the airfoil deflects the oncoming air (for fixed-wing aircraft, a downward force), resulting in a force on the airfoil in the direction opposite to the
