Question

The CGs unit of visosity is poise (P). Find how many poise are there in 1 MKS unit of viscosity called poiseuille (PI)?

Answer 1

Correct Answer - 10 poise
SI unit of cofficient of viscosity is `Ns m^(-2)` and is called decapoise.
1 decapoise `=1 Ns m^(-2)`
`=(10^(5)" dyn")xxsxx(10^(2) cm)^(-2)`
`=10` dyn s `cm^(-2)= 10` poise
