The relative velocity of two parallel la...

The relative velocity of two parallel layers of water is 8 cm/sec. If the perpendicular distance between the layers is 0.1cm. The velocity gradient will be:

A

80/sec

B

60/sec

C

50/sec

D

40/sec

Text Solution

Verified by Experts

The correct Answer is:
A

dv = 8cm/s and dx = 0.1 cm
velocity gradient `=(dv)/(dx)=(8)/(0.1)=80//sec`
