Question 1

What is the vertical component of pressure force on submerged curved surface equal to?

Question 2

A house-top water tank is made of flat plates and is full to the brim. its height is twice that of any side. The ratio of total thrust force on the bottom of the tank to that on any side will be:

Question 3

A vessel containing water of depth h is accelerated upward with an acceleration of g/2. The pressure at the bottom of the vessel is?

Question 4

A semicircular plane area of diameter 1m, is subjected to a uniform gas pressure of 420kN/m². What is the moment of thrust (approximately) on the area about its straight edge?

Question 5

Determine the magnitude of hydrostatic force per unit width of the curved surface AB in vertical direction. The curved surface forms a quadrant of circle of radius 1.8 m as shown in in figure.

Question 6

The magnitude of the buoyant force can be determined by :

Question 7

Consider the figure below relating to buoyancy in water.

What will be the downward force upon the top of the body ABCOEF?

Question 8

In a floating body I = Moment of inertia of water line area about the longitudinal axis,

= Volume of displaced fluid, B = Centre of pressure, G = Centre of gravity and M = Metacentre. For stable equilibrium of this body

Question 9

Statement (I): For stability of floating bodies, center of gravity(G) will always be below center of buoyancy(B).

Statement (II): When B is above G then small angular displacement will set up a restoring couple which will bring the body back to its original position.

Question 10

A rectangular pontoon has a width of 6 m, a length of 12 m and a draught of 1.5 m in fresh water (density = 1000 kg/m³). It's draught in sea water having density of 1025 kg/m³ is
