गोलाकार-भाग हिंदी उपयोग और उदाहरण

अधिकाँश गैलेक्सियों का केंद्र तारों से भरा हुआ गोलाकार भाग होता है, जिसे नाभिक कहा जाता है और यह नाभिक अपने चारों ओर एक तलीय गोलाकार डिस्क से जुडा होता है।

"" साथ साथ अंडों के नुकीले भाग घोंसले के मध्य में केंद्रित हो जाने और उनका गोलाकार भाग बाहर की ओर होने से, यदि घोंसले में तीन चार अंडे हों तो वे सभी आसानी से अँट जाते हैं।

गोलाकार-भाग इसके अंग्रेजी अर्थ का उदाहरण

D \frac{k_\text{B} T}{6\pi\,\eta\,r} (Stokes–Einstein equation, for diffusion of spherical particles through a liquid with low Reynolds number).

r is the radius of the spherical particle.

For spherical particles of radius r, Stokes' law gives.

It can be shown that the virtual mass force, for a spherical particle submerged in an inviscid, incompressible fluid is.

where bold symbols denote vectors, \mathbf{u} is the fluid flow velocity, \mathbf{v} is the spherical particle velocity, \rho_\mathrm{c} is the mass density of the fluid (continuous phase), V_\mathrm{p} is the volume of the particle, and D/Dt denotes the material derivative.

The viscous resistance for a spherical particle is given by Stokes' law: 6πηr0v, where η is the viscosity of the medium, r0 is the radius of the particle and v is the velocity of the particle.

The terminal velocity for a spherical particle is given by the equation:.

Also for non-spherical particles of a given shape, is proportional to and inversely proportional to some specific dimension.

The field enhancement is greatest when the plasmon frequency, ωp, is in resonance with the radiation (\omega \omega_p/\sqrt 3 for spherical particles).

For a volume fraction Fv of randomly distributed spherical particles of radius r, the number per unit volume (number density) is given by.

As time trends to infinity, the entire population of particles becomes one large spherical particle to minimize the total surface area.

It can be suppressed by adding elongated particles, such as cellulose fibers, to the spherical particles that cause the coffee-ring effect.

Convective deposition can control particle orientation, resulting in the formation of crystalline monolayer films from nonspherical particles such as hemispherical, dimer, and dumbbell shaped particles.

Such thickness transitions were established with spherical particles as well.
