Answer - One decapoise is equal to one pascal second which is also equal to ten poise.
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. The term "viscosity" can also be used to describe a fluid's thickness or resistance to being penetrated by foreign objects.
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. A fluid with low viscosity, on the other hand, flows smoothly because its molecular structure causes less friction when it is in motion. Viscosity is also present in gases, but it is less obvious in everyday situations.
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 one pascal second which is further equal to ten poise.
