One Decapoise is Equal to the one-pascal second, which is equal to ten poise. Most people know that the SI unit for viscosity, or dynamic viscosity, is poise. We frequently see that the word poise always has a certain prefix to make it the unit that may precisely describe the viscosity of water.

Value of One Decapoise

We refer to this resistance to motion that most fluids provide as “viscosity.” When there is relative motion between the fluid’s layers, viscosity develops. More specifically, it measures flow resistance brought on by internal friction between fluid layers that occur when they pass one another during fluid flow.

Strong intermolecular forces provide a lot of internal friction in a fluid with a high viscosity, which makes it difficult for layers to move past one another. On the other hand, a fluid with low viscosity flows smoothly because its molecular structure causes less friction when it is in motion.

  • Viscosity is measured in SI units, poiseiulle (PI).
  • Newton-second per square metre (N s m-2) and pascal-second are some of its other units (Pa s.). [ML-1T-1] is the dimensional formula for viscosity.
  • Ten poise are equal to one decapoise, one pascal second, and one decapoise.


One Decapoise is Equal to

One Decapoise is Equal to Ten Poise. Viscosity is measured in Decapoise, which indicates it is 10 times as one poise. It is essentially the SI unit, often known as the Pascal second or by other names. The term “viscosity” can also be used to describe a fluid’s thickness or resistance to being penetrated by foreign objects. Viscosity is also present in gases but is less obvious in everyday situations.
