A bottle contained a mixture of two liquids A and B in the ratio 11 ∶ 4. When 30 ml of the mixture is replaced with 15 ml of another mixture of the two liquids in ratio 7 ∶ 8, the ratio of the liquids in the final mixture becomes 2 ∶ 1. What is the quantity of final mixture in the bottle?
A container has a mixture of liquids A and B. The ratio of liquids A to B is 4 : 5. How much mixture must be taken out of the container and replaced with liquid A so that the final mixture should contain liquids A and B in ratio 1 : 1?

Statement 1: Considering the equation, μ_a= τ/γ = Kγ(n-1) , for pseudo plastic fluids, n<1 and they’re called Shear thinning liquids and dilatant fluids are called Shear thickening liquids as n>1. Statement 2: Cooked starch solution is a Shear thinning liquid and dairy cream is a Shear thickening liquid.

The thermal diffusivities for gases are generally
Less striking effects can arise in ternary systems where all three components diffuse substitutionally if their diffusivities (or mobilities) are unequal.
