Fluid Mechanics Internship Test
Intern has to take Fluid Mechanics internship test in which they will be asked 50 multiple-choice questions. They have to score grade A or A* on this test to be eligible for the internship. Here’s a sample set of questions on the Fluid Mechanics topic.
1. The value of the surface tension of an ideal fluid is
(D) more than that of a real fluid
Explanation: Ideal fluids haze zero surface tension but real fluids have some finite value of surface tension.
2. The specific gravity of a liquid has
(A) the same unit as that of mass density
(B) the same unit as that of weight density
(C) the same unit as that of specific volume
(D) no unit
Explanation: The specific gravity of a liquid is the ratio of two similar quantities (densities) which makes it unitless.
3. An compressible fluid’s specific gravity was measured on earth, on a planet having acceleration due to gravity 5.5 times that of earth, and in space at STP. Where will it be having highest value?
(A) on the earth
(B) on the planet
(C) in the space
(D) it will be constant everywhere
Explanation: Specific gravity is characteristic property of fluid and is independent of external conditions.
4. Which of the following correctly states how the viscosities of a liquid and a gas will change with temperature?
(A) Viscosity increases with the increase in temperature of a liquid and decreases with the increase in temperature of a gas
(B) Viscosity increases with the increase in temperature of a liquid and increases with the increase in temperature of a gas
(C) Viscosity decreases with the increase in temperature of a liquid and decreases with the increase in temperature of a gas
(D) Viscosity decreases with the increase in temperature of a liquid and increases with the increase in temperature of a gas
Explanation: Viscosity of a liquid is due to the cohesion between it’s molecules. With the increase in temperature of a liquid, cohesion increases, leading to the rise in viscosity. Viscosity of a gas is due to the momentum transfer between it’s molecules. With the increase in the temperature of a liquid, molecular motion increases, leading to the fall in viscosity.
5. For a compressible fluid the kinematic viscosity is affected by temperature and pressure variation.
Explanation: Viscosity shows variation for change in temperature and pressure for compressible fluids. Hence, kinematic viscosity is affected by temperature and pressure variation.
