Tardigrade Admin · Accepted Answer

The S.I unit of coefficient of viscosity is Nm -2 sec. The C.G.S unit of viscosity is dyne cm -2 sec which is equal to 1 poise. 1 poise =10-1 Nm -2 sec

Q. Which of the following expressions regarding the unit of coefficient of viscosity is not true?

dyne $c m^{- 2} sec$

dyne $c m^{2} se c^{- 1}$

$N m^{- 2} sec$

$1$ poise $= 1 0^{- 1} N m^{- 2} sec$

The S.I unit of coefficient of viscosity is $N m^{- 2}$ sec. The C.G.S unit of viscosity is dyne $c m^{- 2}$ sec which is equal to 1 poise.
1 poise $= 1 0^{- 1} N m^{- 2} sec$

Q. Which of the following expressions regarding the unit of coefficient of viscosity is not true?

dyne cm−2sec

dyne cm2sec−1

Nm−2sec

1 poise =10−1Nm−2sec

The S.I unit of coefficient of viscosity is Nm−2 sec. The C.G.S unit of viscosity is dyne cm−2 sec which is equal to 1 poise. 1 poise =10−1Nm−2sec

dyne $c m^{- 2} sec$

dyne $c m^{2} se c^{- 1}$

$N m^{- 2} sec$

$1$ poise $= 1 0^{- 1} N m^{- 2} sec$

The S.I unit of coefficient of viscosity is $N m^{- 2}$ sec. The C.G.S unit of viscosity is dyne $c m^{- 2}$ sec which is equal to 1 poise.
1 poise $= 1 0^{- 1} N m^{- 2} sec$
