Fluid Mechanics MCQ with Answers

11) The value of mass density in kgsecVm4 for water at 0°C is

Answer is:

101.9

12) Property of a fluid by which its own molecules are attracted is called

Answer is:

cohesion

13) Mercury does not wet glass. This is due to property of liquid known as

Answer is:

surface tension

Explanation:

Mercury does not wet glass - the cohesive forces within the drops are stronger than the adhesive forces between the drops and glass. When liquid mercury is confined in a tube, its surface (meniscus) has a convex shape because the cohesive forces in liquid mercury tend to draw it into a drop.
