When an incompressible liquid flows steadily over a solid surface, the liquid close to the surface experiences a significant retardation. The liquid velocity is zero at the surface (provided that the no-slip boundary condition holds) and gradually increases with distance from the surface, and a ve...
An incompressible liquid flows through a horizontal tube as shown in the figure. Then the velocity 'v' of the fluid is: View Solution When two liquids A and B of equal weight are filled inside two identical containers, the height of the liquid Column A is greater than the height of the...

Magnetic nanoparticles are suspended colloidally in a carrier liquid to form ferrofluids. To make ferrofluid, at least three ingredients are necessary: carrier liquid, nano-sized magnetic particles, and surfactants. Ferrofluids are primarily employed in the hard disc drive sealing process. Ferrofluids are...
The transition to a liquid state is only observed below T~4.8K, and it is manifested by a clear spontaneous spatial condensation to a smaller and denser cloud. This cloud maintains its size, energy, and linewidth over two-orders-of-magnitude increase in the optical excitation power. This ...
In “Constitutive modeling”, a generalized constitutive relation is developed for an incompressible isotropic non-Newtonian EMR fluid under an electromagnetic field. Next, in “Application to few standard fluid flow situations”, the developed constitutive relation is applied to an ER fluid valve ...
A study is made of the plane convergent forced flow of an incompressible liquid with anomalous viscosity, whose rheological properties obey a power law. A reduction in flow cross section leads to the development of a counterpressure whose existence produces near the inlet a counterflow in the regi...
(volumetric flow) of incompressible liquids is measured, the presence of suspended bubbles will cause error, therefore, air and gas must be removed before the fluid reaches the meter. In other velocity sensors, pipe liners can cause problems (ultrasonic), or the meter may stop functioning if ...
17 His theory is based on the Boussinesq equations (Section 2.3) applied to an incompressible fluid that expands as its temperature is increased. For such a fluid the buoyancy is given by (2.171)B=gaT′ where a is the expansion coefficient, defined such that ρ′/ρo=−aT′. Friction ...
The chapter discusses the solvability "in the small" of the nonstationary problem of an ideal-liquid flowing through a bounded domain when on the portion of inflowing the total vector of velocity is given, while on the portion of outflowing—its normal component. N. E. Kotchin first ...
