Frequently Asked Questions
-
What does one dekapoise represent in terms of viscosity?
-
A dekapoise (daP) is a cgs-derived unit of dynamic viscosity equal to 10 poise and corresponds to 1 pascal-second in the SI system, measuring a fluid's resistance to shear flow.
-
Why convert from dekapoise to pound/foot/hour?
-
Converting to pound/foot/hour allows expressing dynamic viscosity in imperial units, facilitating use in engineering fields and regions that apply customary measurement systems, especially for lubricants and industrial fluids.
-
Are there considerations when converting these viscosity units?
-
Yes, users should consider the difference in time units (seconds vs. hours) and ensure precision due to sensitivity in viscosity measurements, as well as conform to regional and instrument calibration standards.
