What else can I help you with?
Which method represents of heat in a fluid?
Heat conduction is the method that represents the transfer of heat in a fluid. Heat is transferred from particle to particle through direct contact within the fluid.
Use the particle model to explain buoyancy?
In the particle model, buoyancy can be explained by the upward force exerted by fluid particles on an object immersed in the fluid. When an object is placed in a fluid, the fluid particles push against the object from all sides, creating an upward force known as buoyant force. The buoyant force is dependent on the volume of the object submerged in the fluid and the density of the fluid.
How does a cell perform?
A cell performs pinocytosis when it needs a fluid that's outside of the cell. It does this by taking in the fluid particle in through the cell membrane. It wraps the particle in a layer of the membrane. See the related link for an example.
What is the physical significance of curl?
curl is clear from observation that many fluid flows involvs rotational motion of the fluid particle.
How does understand particle motion help you understand fluid pressure?
Understanding particle motion helps in understanding fluid pressure because pressure in a fluid is determined by the motion and collisions of its particles. When particles move faster or collide more frequently, the pressure of the fluid increases. This relationship is described by Bernoulli's principle, which relates the speed of fluid flow to its pressure.
What is the function of a reticulum?
The fluid contents of the reticulum play a role in particle separation.
Velocity of a fluid particle at centre of pipe is?
The velocity of a fluid particle at the center of a pipe in a fully developed flow is half of the maximum velocity in the pipe. This is known as the Hagen-Poiseuille flow profile for laminar flow.
What is the derivation of Stokes' Law?
Stokes' Law is derived from the balance of forces acting on a small spherical particle moving through a viscous fluid at low Reynolds numbers. The law describes the drag force experienced by the particle as it moves through the fluid.
Use particle diagram to explain conduction and convection?
In conduction, heat transfer occurs through direct contact between particles. When a hot particle collides with a cold particle, it transfers thermal energy. In convection, heat transfer occurs through the movement of particles in a fluid. Hot fluid rises due to decreased density, while cold fluid sinks, creating a continuous cycle of heat transfer.
The movement of a substance into a cell by a vesicle is called?
Phagocytosis if a particle was absorbed. Pinocytosis if a fluid was absorbed.
What is the settling velocity in specific gravity of the solid particles?
The settling velocity of solid particles in a fluid depends on the size, shape, density difference, and viscosity of the fluid. It can be calculated using Stokes' law, which considers these factors to determine the terminal velocity of a particle settling under gravity in a fluid. The settling velocity increases with increasing density difference and particle size, and decreases with increasing fluid viscosity.
What is the non example of particle?
A non-example of a particle would be a continuous, unbroken physical substance, such as a fluid or gas. These substances do not consist of individual, distinct particles like atoms or molecules.
