Water at 20°C ( coefficient of viscosity= 0.01 poise) flowing in a tube of diameter 1 cm with an average velocity of 10 emfs has the Reynold number:

A

500

B

1000

C

2000

D

indeterminate due to insufficient data.

Text Solution

Verified by Experts

The correct Answer is:
B

Reynold number is given by
`N=(pvD)/(eta)` where p is density, v is velocity & D is diameter of the tube.
`N=(1xx10xx1)/(0.01)`
`N=1000`
so correct choice is (b).
