Fluid Mechanics Assignment No.1

Fluid Mechanics

Assignment no. 1

1.      Is surface tension & capillarity dependent on density of liquid? If yes, How? If no, Why?

2.      On what factor does the capillarity of a liquid depends and how? Explain.

3.      Can a liquid be boiled at ordinary temp? (Room temp.). Justify.

4.      Explain Cavitation.

5.      How the Stability of Floating bodies effected by the position of centre of gravity & centre of buoyancy?

6.      Why the shop floats in water while the needle sinks? Explain.

7.      A Circular thin plate, 500mm dia. is immersed in water vertically such that its top edge is 2m below the free water surface. Find the total hydrostatic pressure acting on the plate & position of its centre of pressure.

8.      A triangle surface 1m base and 1.5m altitude is placed in a liquid of specific gravity 0.80. The plane of the area is inclined 30º to the liquid surface and the base is parallel to and at a depth of 2m from the free surface. Determine the total pressure and the position of centre of pressure.

9.      A triangle lamina of base 500mm and height 750mm is hanged vertically inside tank containing glycerin of specific gravity 1.26 such that its base coincides with the free surface. Determine the glycerin pressure acting on one side of the lamina and depth of centre of this pressure.

10.  a tank contains water upto a height of 1 m above the base a liquid or specific gravity 0.8 is filled on the top of water upto 1.5 m height calculate (i) total pressure on one side of the tank (ii) the position of centre of pressure for one side of the tank which is 3 m wide.
