28 cze 2024 · The terminal velocity acquired by the ball of radius r r when dropped through a liquid of viscosity η η and density ρ ρ is, v = 2r2(ρo − ρ) g 9η v = 2 r 2 ( ρ o − ρ) g 9 η. Note :Terminal velocity is defined as the maximum velocity attained by a body as it falls through a fluid.
13 cze 2024 · Terminal velocity equation | Image: Learnool. Terminal velocity is the constant speed that a freely falling object eventually reaches when the resistance of the medium through which it is falling prevents further acceleration. As an object falls, gravity pulls it downward, causing it to accelerate.
4 dni temu · Hint: This question can be solved using the general formula for terminal velocity of a fluid which is given as $v = \dfrac{2}{9}\dfrac{{{r^2}\left( {\rho - \sigma } \right)g}}{\eta }$. By substituting the value of radius r, coefficient of viscosity $\eta $and density of water $\rho$ and density of air $\sigma$ given in the question we find the ...
6 dni temu · The formula for viscosity shows that the terminal velocity (v) is proportional to the radius squared; v is greater for a larger sphere than for a smaller one of the same material.
28 cze 2024 · The maximum constant velocity acquired by a body while falling through a viscous fluid is called its terminal velocity. Mathematically terminal velocity is given as, $V=\dfrac{2}{9}{{r}^{2}}=\dfrac{\left( \rho -\sigma \right)g}{\eta }$
26 cze 2024 · Terminal Velocity Formula. The terminal velocity (\ (v_t\)) of an object is calculated using the equation: \ [ v_t = \sqrt {\frac {2mg} {\rho A C_d}} \] where: \ (m\) is the mass of the object, \ (g\) is the acceleration due to gravity, \ (\rho\) is the density of the medium (air), \ (A\) is the cross-sectional area, and.
