Hydrostatic Forces

What is the formula to calculate pressure at a point in a fluid?

• P = ρgh

• P = ρh/g

• P = ρg/h

• P = 2ρgh

Centre of pressure is the effective point of application of pressure distributed over a surface
.

• Yes

• No

Chose the formula to calculate the vertical force (Fv) for curved surface?

• 
• 
• 
• 

Define the term 'hydrostatic pressure'.

• Pressure exerted by a gas at equilibrium

• Pressure exerted by a fluid in motion

• Pressure exerted by a fluid at equilibrium due to the force of gravity

• Pressure exerted by a solid object in a fluid

What is the significance of determining the center of pressure on a submerged surface?

• It helps in understanding the distribution of hydrostatic forces.

• The center of pressure is irrelevant in hydrodynamics.

• It only affects the buoyancy of the submerged surface.

• It has no significance in determining the distribution of hydrostatic forces.

How does the shape of a submerged surface affect the hydrostatic force acting on it?

• It changes the distribution of pressure across the surface.

• It has no effect on the hydrostatic force

• It changes the color of the water

• It increases the temperature of the water

Explain the concept of resultant hydrostatic force on a submerged surface.

• The pressure exerted by the fluid on the surface

• The total force exerted by the fluid on the surface due to the pressure distribution.

• The weight of the fluid on the surface

• The force exerted by the surface on the fluid

Discuss the applications of hydrostatic forces in engineering and construction.

• Dams, retaining walls, hydraulic structures, buoyancy, stability

• Painting, sculpture, music

• Agriculture, transportation, communication

• Chemical reactions, biological processes, nuclear physics
