One poise (unit of absolute/dynamic viscosity) is equivalent to one_____________________?
Correct answer: B. gm/cm. sec
- A. gm/cm2. sec
- B. gm/cm. sec
- C. cm2/sec
- D. m2/sec
Explanation
Dynamic viscosity has dimensions mass divided by length-time; in CGS units, one poise equals 1 g/(cm·s). The unit cm²/s is instead a kinematic-viscosity unit.
