Viscosity of ethanol is 12.0 millipoise. Viscosity of ethanol in S.I s

1.	Viscosity of ethanol is 12.0 millipoise. Viscosity of ethanol in S.I system is equal to
Answer» `1.2` `1.2 xx 10^(-3)` `1.2 xx 10^(-2)` `1.2 xx 10^(-1)` Solution :12 m poise = `12 xx 10^(-3) ` poise. 1 poise = CGS unit = `(1 GM)/(Cm - S) = (10^(-3)KG)/(10^(-2) m - s)` `= 0.1 SI UNITS = 12 xx 10^(-3) ` poise ` = 12 xx 10^(-3) xx 0.1 kg//m-s = 1.2 xx 10^(-3)`.
