Viscosity converters translate between kinematic (stokes, cSt) and dynamic (poise, centipoise, Pa·s) viscosity units.
Формула
Kinematic = dynamic / density: ν = μ / ρ
Пошаговое руководство
- 1Kinematic = dynamic / density: ν = μ / ρ
- 21 cSt = 0.01 stokes = 0.000001 m²/s
- 31 centipoise (cP) = 0.001 Pa·s = 0.001 kg/(m·s)
Решённые примеры
Ввод
Motor oil SAE 10W-30: 100 cSt at 40°C, density 0.88 kg/L
Результат
Dynamic viscosity ≈ 88 cP
Temperature-dependent
Распространённые ошибки
- ✕Confusing kinematic and dynamic viscosity without conversion
- ✕Using room-temperature viscosity for high-temperature flow
Часто задаваемые вопросы
Why two types of viscosity?
Dynamic used with pressure drop calculations, kinematic for fluid flow under gravity. Related by density.
How temperature sensitive is viscosity?
Dramatically; halving oil temperature can double viscosity. Viscosity index rates this sensitivity.
