Fluid Mechanics Viscosity Question 206

Question: Equal masses of water and a liquid of density 2 are mixed together, then the mixture has a density of

Options:

A)2/3

B)4/3

C)3/2

D)3

Show Answer

Answer:

Correct Answer: B

Solution:

If two liquid of equal masses and different densities are mixed together then density of mixture$ \rho =\frac{2{\rho_{1}}{\rho_{2}}}{{\rho_{1}}+{\rho_{2}}}=\frac{2\times 1\times 2}{1+2}=\frac{4}{3} $
