Viscosity converters translate between kinematic (stokes, cSt) and dynamic (poise, centipoise, Pa·s) viscosity units.
Công thức
Kinematic = dynamic / density: ν = μ / ρ
Hướng dẫn từng bước
- 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)
Ví dụ có lời giải
đầu vào
Motor oil SAE 10W-30: 100 cSt at 40°C, density 0.88 kg/L
Kết quả
Dynamic viscosity ≈ 88 cP
Temperature-dependent
Lỗi thường gặp cần tránh
- ✕Confusing kinematic and dynamic viscosity without conversion
- ✕Using room-temperature viscosity for high-temperature flow
Câu hỏi thường gặp
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.
