Why streamlined bodies can move faster in liquid and air than non streamlined bodies?

The reason streamlined bodies can move faster in liquid and air is because they have less surface area to cause resistance. For instance, on a windy day, an open umbrella has more resistance and can get caught up in the wind but a closed one with less resistanceÊcan not.


Why does an ideal fluid move faster through a pipe with decreasing diameter?

The pressure within the fluid decreases


How do molecules move in fluid?

Molecules move in a fluid the same way they move through anything else. If the fluid is warmer, they move faster.


What are the benefits of stream lined bodies?

Streamlined bodies reduce drag as they move through a fluid, allowing for faster movement with less resistance. This is particularly advantageous in swimming, cycling, and other sports where speed is a key factor. Streamlined bodies also help to improve efficiency and reduce energy expenditure.


What happens to a fluid when it warms?

When a fluid warms up, its particles gain energy and move faster, which causes the fluid to expand and become less dense. This can lead to a decrease in viscosity and an increase in kinetic energy, resulting in faster flow rates. Additionally, changes in temperature can also affect the solubility of solutes in the fluid.


What happens to a fluid when temperature increases?

The particles within the liquid begin to accelerate, and colide at a faster rate as the temperature of the solution increases. This causes the particles to move further, and further away from each other as the inter-molecular bonds holding the molecules begin to weaken.


Compare to a cold fluid how would the particles in a hot fluid be moving?

Faster. This assumes the same type of atoms or molecules.


Why do streamline bodies move faster in liquids?

Streamlined bodies have a shape that reduces drag as they move through a liquid, allowing them to move faster with less resistance. The streamlined shape helps to minimize boundary layer separation and vortex shedding, which are major causes of drag in flow around an object. This reduction in drag allows the body to move more efficiently through the liquid.


What happens to a fluid when it heats?

When the liquid molecules are heated, they move faster so the liquid boils and some molecules becomes gas molecules. When the liquid molecules are heated, they move faster so the liquid boils and some molecules becomes gas molecules.


What happens to molecules in a heated fluid?

In a heated fluid, molecules gain kinetic energy, causing them to move faster and collide more frequently. This increased movement results in the expansion of the fluid, as the molecules move apart from each other. Additionally, the increased temperature can lead to changes in the physical state of the fluid, such as boiling or evaporation.


What happens when density fluid gets hotter?

When the density of a fluid increases due to heating, the molecules within the fluid move faster and spread further apart, causing the fluid to expand. This expansion leads to a decrease in density, as the same mass now occupies a larger volume.


Why does viscosity vary with respect to temperature?

the increase in temperature increases the K.E of the molecules and distances among molecules therefore the force of friction decreases as the result of which molecules move faster and viscosity becomes decreased....
