The factors that affect terminal velocity in a fluid include the weight and size of the object, the density and viscosity of the fluid, and the shape of the object. Objects with a larger surface area or lower weight will reach terminal velocity faster, while denser fluids or more streamlined objects will increase terminal velocity.

What is the difference between terminal speed and terminal velocity?
The difference between terminal speed and terminal velocity is really simple. Terminal speed can be used to refer to the maximum speed an object can reach before factors like friction prevent anymore speed to be gained. Terminal velocity, however, generally refers to the rate at which this speed was gained.
What is the speed at which particles of sediment fall through a still fluid?
The speed at which particles of sediment fall through a still fluid is influenced by factors such as the size and density of the particles, as well as the viscosity of the fluid. This settling velocity can be calculated using Stokes' law, which takes into account these factors to determine the terminal velocity of the particles.
What are some characteristics of terminal velocity?
Terminal velocity is the constant speed reached by an object falling through a fluid, when the force of gravity is balanced by the drag force. The object stops accelerating and falls at a steady velocity. Terminal velocity depends on the mass, size, and shape of the object and the properties of the fluid it is falling through.
What is the terminal velocity of a sphere falling through a fluid?
The terminal velocity of a sphere falling through a fluid is the constant speed at which the force of gravity pulling the sphere down is balanced by the resistance of the fluid pushing against it. This velocity depends on the size, shape, and density of the sphere, as well as the viscosity and density of the fluid.
What is the formula to calculate the terminal velocity of a sphere falling through a fluid?
The formula to calculate the terminal velocity of a sphere falling through a fluid is given by: Vt frac29 frac(rhos - rhof)gR2eta where: ( Vt ) is the terminal velocity ( rhos ) is the density of the sphere ( rhof ) is the density of the fluid ( g ) is the acceleration due to gravity ( R ) is the radius of the sphere ( eta ) is the viscosity of the fluid
How does concentration of a fluid affect the motion of falling objects?
The higher the concentration of a fluid, the longer the time it takes for an object to fall and therefore the smaller the terminal velocity.

What factors affect fluid resistance?
Factors that affect fluid resistance include the viscosity of the fluid, the velocity of the fluid flow, the diameter of the pipe or channel through which the fluid is flowing, and the length of the pipe or channel. Additionally, the roughness of the pipe walls and any obstacles or bends in the flow path can also impact fluid resistance.
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 do you mean by critical velocity by method of dimensions establish its relation?
Critical velocity is the minimum velocity required for an object to overcome a particular resistance force. By using the method of dimensions, you can establish a relationship between critical velocity and the factors that influence it, such as the viscosity of the fluid, density of the fluid, and the size and shape of the object. By analyzing the dimensions of these factors and the force equation, you can derive an equation that relates critical velocity to these variables.
What is terminal velocity dependent upon?
Terminal velocity is dependent on the drag force acting on an object and its weight. As an object falls through a fluid (like air or water), the drag force increases until it balances out the weight of the object, causing it to stop accelerating and to fall at a constant speed known as terminal velocity. The shape and size of the object, as well as the density of the fluid it is falling through, also impact its terminal velocity.
How high do you have to be to reach terminal velocity?
Terminal velocity is the maximum speed an object reaches when falling through a fluid (such as air) due to balance between gravity and air resistance. The exact height you need to reach to achieve terminal velocity varies depending on factors like your weight, body position, and the specific characteristics of the air around you. In a general sense, skydivers typically reach terminal velocity within about 10-12 seconds of freefall from an altitude of around 12,000 feet.
Do bubbles reach terminal velocity?
It depends on the type of bubbles. Hydrogen bubbles are often used to visualize aerodynamic flows around models. How you would work out their terminal velocity is by balancing their drag force and buoyancy force. First you would need an estimate of the bubble diameter, somewhere around .025 mm. For water, density of fluid =998 kg/m3 and fluid viscosity = 1.12*10-3 Pa*s FB=density of fluid*volume of bubble*gravity FD=3*pi*fluid viscosity*diameter*velocity of water At the terminal velocity FD=FB, you should have all the other variables, just rearrange to solve for the terminal velocity.
