Pick out the wrong conversion of absolute & kinematic viscosities ?
Correct answer: C. 1 stoke = 1 m2/sec
- A. 1 stoke = 1 cm2/sec
- B. 1 N.sec/m2 = 10 paise
- C. 1 stoke = 1 m2/sec
- D. 1 m2/sec = 104 stokes
Explanation
A stoke is 1 cm²/s, whereas 1 m²/s equals 10^4 stokes. Therefore, the statement that 1 stoke equals 1 m²/s is the incorrect conversion; also, 1 N·s/m² equals 10 poise.
