Question

If a fluid, which has a constant specific gravity, is taken to a planet where acceleration due to gravity is 3 times compared to its value on earth, what will happen to its kinematic viscosity.

(a) It increases

(b) It decreases

(c) It remains constant

(d) None of the above

I had been asked this question by my college professor while I was bunking the class.

My question is based upon Viscosity in section Properties of Fluids of Fluid Mechanics

Answer 1

Right choice is (c) It remains constant

The best I can explain: Kinematic viscosity depends on density and dynamic viscosity. Both, density and dynamic viscosity, are independent of acceleration due to gravity. Therefore, kinematic viscosity is independent of acceleration due to gravity.
