If two liquids of same volume but different densities ρ1 and ρ2 are mixed, then density of mixture is given
Correct answer: C. ρ= 2ρ1ρ2/ρ1+ρ2
- A. ρ= ρ1+ρ2/2
- B. ρ= ρ1+ρ2/2ρ1ρ2
- C. ρ= 2ρ1ρ2/ρ1+ρ2
- D. ρ= ρ1ρ2/ρ1+ρ2
Explanation
If two liquids have equal volumes, then the density of the mixture is simply the harmonic mean of the two densities:𝜌 mix=Total mass/ Total volumeρ mix=Total volume\Total massl

About Fluid Dynamics
Fluid flow is described through speed, pressure and density, including steady flow and the equation of continuity for conserving mass. Bernoulli's equation relates pressure, speed and height, while fluid drag and terminal velocity explain why a falling object eventually moves at constant speed when drag balances its weight.
