variation of pressure

if a diver goes from a depth of 5m to 10m in water, the pressure due to water on the diver will:

• double

• halve

• remain the same

• increase by four times

fluid pressure depends upon____

• height

• velocity

• density

• both (a) and (c)

What do you mean by Pascal law?

• For every action, there is an equal and opposite reaction

• Force is the time rate of change of momentum

• For an ideal gas, the pressure is directly proportional to temperature and constant volume and mass

• pressure in a fluid at rest is same at all points which are at the same height

which of the following statements is true about pressure in a fluid at a given depth?

• Pressure increases horizontally

• Pressure is the same in all directions

• Pressure decreases vertically

• Pressure varies with temperature only

In a fluid, if the density is increased by 20% while maintaining the same depth, how does the pressure change?

• decrease by 20%

• increase by 10%

• decrease by 40%

• increase by 20%

As we go above in a liquid column, the amount of pressure will?

• increase

• no change

• decrease

• none of the given

Absolute pressure means?

• the atmospheric pressure at sea level

• the atmospheric pressure expressed in Kg/cm²

• the pressure is equal to the algebraic sum of atmospheric and gauge pressure

• the pressure as seen on the gauge of a pressure measuring instrument

Hydrostatic Paradox follows which law/principle?

• Bernoulli's Principle

• Archimedes principle

• pascals law

• both (a) and (b)

Which of the following best describes the hydrostatic paradox?

• The pressure in a fluid depends on the shape of the container

• The pressure in a fluid increases with the volume of the container

• The pressure at a given depth in a fluid is independent of the shape or volume of the container

• The pressure at a given depth in a fluid is dependent on the total volume of the fluid.

Which equation represents the pressure at a given depth in a fluid according to the hydrostatic paradox?

• P=ρh

• P=ρg

• P=gh

• P=ρgh
