About Pascal-seconds
The pascal-second (Pa·s) is the SI coherent unit of dynamic viscosity, equal to 1 kg/(m·s) = 1 N·s/m². Honey at 25 °C is ≈2-10 Pa·s; glycerol ≈1.4 Pa·s; bitumen 10⁴-10⁸ Pa·s. It replaced the poise in SI usage and is the standard unit in research and simulation software (CFD, process simulators). 1 Pa·s = 10 P = 1 000 cP.
About Pounds per foot-hour
The pound per foot-hour (lb/(ft·h)) equals 0.45359237 / (0.3048 × 3600) ≈ 4.134×10⁻⁴ Pa·s. It appears in US heat-transfer and mass-transfer textbooks (e.g., McCabe, Smith & Harriott) where viscosity enters the Reynolds number using consistent hour-based units alongside BTU, ft, and lb quantities. Water at 20 °C is ≈2.42 lb/(ft·h). 1 lb/(ft·h) ≈ 4.134×10⁻⁴ Pa·s.
