Fluid Mechanics MCQ with Answers

36) The stress-strain relation of the newtonian fluid is

Answer is:

linear

Explanation:

A Newtonian fluid is defined as one with constant viscosity, with zero shear rate at zero shear stress, that is, the shear rate is directly proportional to the shear stress.

The stress-strain relation of the newtonian fluid is

37) A liquid compressed in cylinder has a volume of 0.04 m3 at 50 kg/cm2 and a volume of 0.039 m3 at 150 kg/cm2. The bulk modulus of elasticity of liquid is

Answer is:

4000 kg/cm2

38) The units of viscosity are

Answer is:

kg sec/metre

39) Kinematic viscosity is dependent upon

Answer is:

density

Explanation:

Kinematic viscosity. It is defined as the ratio of dynamic viscosity to the density of liquid.
