1.	A gas bubble of diameter 002 m rises steadily at the rate of 2.5 10^(-2) ms^(-1)through a solution of density 2.5 xx 10^(3)kg m ^(-3) . Calculate the coefficient of viscosity of the solution. Neglect the density of the gas.
Answer» Solution :` ETA = 2 XX (0.01)^(2) xx 2.5 xx 10 ^(3)xx 9.8//9 xx 2.5 xx10 ^(-2)= 2.18 xx 10 ^(-2)NSM ^(-2)`
