Properties of Fluids

Front

What is Bernoulli's Principle?

Back

Bernoulli's Principle states that in a stream of fast-moving fluid, the pressure exerted by the fluid is lower than the pressure exerted by the surrounding fluid.

Front

What is lift in the context of fluids?

Back

Lift is an upward force that acts on an object immersed in a fluid, counteracting the force of gravity.

Front

What happens to an object with a density greater than water when placed in water?

Back

It will sink.

Front

What does Pascal's Principle state?

Back

Pascal's Principle states that when a force is applied to a confined fluid, the increase in pressure is transmitted equally throughout the fluid.

Front

In which direction does buoyant force act?

Back

Buoyant force always acts upward.

Front

What is Archimedes' Principle?

Back

Archimedes' Principle states that an object submerged in a fluid experiences a buoyant force equal to the weight of the fluid displaced by the object.

Front

Define viscosity.

Back

Viscosity is a measure of a fluid's resistance to flow or deformation.

Front

What is the relationship between pressure and depth in a fluid?

Back

Pressure increases with depth in a fluid due to the weight of the fluid above.

Front

What is the formula for calculating pressure in a fluid?

Back

Pressure (P) = Force (F) / Area (A).

Front

What is the significance of the continuity equation in fluid dynamics?

Back

The continuity equation states that the mass flow rate must remain constant from one cross-section of a pipe to another, implying that fluid velocity increases as the cross-sectional area decreases.
