Correct answer: C. Nearly equal to water
- A. More than water
- B. Less than that of water
- C. Nearly equal to water
- D. 3 times greater than water
Explanation
According to Punjab Text Book, Chapter 6, page 137 (Topic: Blood flow) 1st line: "Blood is an incompressible fluid having a density nearly equal to that for water"

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.
