The density of blood is:

Correct answer: B. Nearly equal to water

  • A. Less than water
  • B. Nearly equal to water
  • C. Greater than water
  • D. Three times that of water

Explanation

Density of water is 1000 kg per metre cube, and the density of blood is 1060 kg per metre cube, making them nearly equal.

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.
