Which of the following statements is correct ?

A

Viscosity is a vector quantity

B

Surface tension is a vector quantity

C

Reynolds number is a dimension quantity

D

Angle of contact is a vector quantity

Text Solution

Verified by Experts

The correct Answer is:
D
Viscosity is a scaler quantity.
hence, option (a) is an incorrect statement ltbr. Surface tension is a scalar quantity .
Hence, option (b) is a incorrect statement.
Reynolds number is a dimensionless quantity.
Hence option (c) is an incorrect statement.
