Which of the given has the least coefficient of viscosity
Correct answer: B. water
- A. milk
- B. water
- C. tar coal
- D. engine oil
Explanation
The coefficient of viscosity are given as followsMilk: 1.5 to 10 mPa·s ∵Pa.s=pascal-secondWater: 0.001 Pa·s Coal Tar: 10,000 to 50,000 mPa·s (viscosity can vary) Engine Oil: 60 to 1000 mPa·s (varies based on type and grade)So, water has the least coefficient of viscosity

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.
